Resumen

As a commonly used solution, the multi-ended readout can measure the depth-of-interaction (DOI) for positron emission tomography (PET) detectors. In the present study, the effects of the multi-ended readout design were investigated using the leading-edge discriminator (LED) triggers on the timing performance of time-of-flight (TOF) PET detectors. At the very first, the photon transmission model of the four detectors, namely, single-ended readout, dual-ended readout, side dual-ended readout, and triple-ended readout, was established in Tracepro. The optical simulation revealed that the light output of the multi-ended readout was higher. Meanwhile, the readout circuit could be triggered earlier. Especially, in the triple-ended readout, the light output at 0.5 ns was observed to be nearly twice that of the single-ended readout after the first scintillating photon was generated. Subsequently, a reference detector was applied to test the multi-ended readout detectors that were constructed from a 6 × 6 × 25 mm3 LYSO crystal. Each module is composed of a crystal coupled with multiple SiPMs. Accordingly, its timing performance was improved by approximately 10% after the compensation of fourth-order polynomial fitting. Finally, the compensated full-width-at-half-maximum (FWHM) coincidence timing resolutions (CTR) of the dual-ended readout, side dual-ended readout, and triple-ended readout were 216.9 ps, 231.0 ps, and 203.6 ps, respectively.

Resumen

Optical readout of Micromegas gaseous detectors has been achieved by implementing a Micromegas detector on a glass substrate with a glass anode and a CMOS camera. Efficient X-ray radio-graphy has been demonstrated due to the integrated imaging approach inherent to optical readout. High granularity values have been reached for low-energy X-rays from radioactive sources and X-ray generators taking advantage of image sensors with several megapixel resolution. Detector characterization under X-ray radiography opens the way to different applications from beta imaging to neutron radiography. Here we will focus on one application: neutron imaging for non-destructive examination of highly gamma-ray emitting objects. This article reports the characterization of the detectors when exposed to a low activity neutron source. The response of the detector to thermal neutrons has been studied with different field configurations and gap thicknesses.

Resumen

Abstract In the last years, optical readout of Micromegas gaseous detectors has been achieved by implementing a Micromegas detector on a glass anode coupled to a CMOS camera. Effective X-ray radiography was demonstrated using integrated imaging approach. High granularity values have been reached for low-energy X-rays from radioactive sources and X-ray generators. Detector characterization with X-ray radiography has led to two applications: neutron imaging for non-destructive examination of highly gamma-ray emitting objects and beta imaging for the single cell activity tagging in the field of oncology drug studies. First measurements investigating the achievable spatial resolution of the glass Micromegas detector at the SOLEIL synchrotron facility with a high-intensity and flat irradiation field will be shown in this article.

Resumen

Abstract Systematic uncertainties in accelerator oscillation neutrino experiments arise from nuclear models describing neutrino-nucleus interactions. To mitigate these uncertainties, we can study neutrino-nuclei interactions with detectors possessing enhanced hadron detection capabilities at energies below the nuclear Fermi level. Gaseous detectors not only lower the particle detection threshold but also enable the investigation of nuclear effects on various nuclei by allowing for changes in the gas composition. This approach provides valuable insights into the modelling of neutrino-nucleus interactions and significantly reduces associated uncertainties. Here, we discuss the design and first operation of a gaseous argon time projection chamber optically read. The detector operates at atmospheric pressure and features a single stage of electron amplification based on a thick GEM. Here, photons are produced with wavelengths in the vacuum ultraviolet regime. In an optical detector, the primary constraint is the light yield. This study explores the possibility of increasing the light by applying a low electric field downstream of the ThGEM. In this region, called the electroluminescence gap, electrons propagate and excite the argon atoms, leading to the subsequent emission of photons. This process occurs without any further electron amplification, and it is demonstrated that the total light yield increases up to three times by applying moderate electric fields of the order of 3 kV/cm. Finally, an indirect method is discussed for determining the photon yield/charge gain of a ThGEM, giving a value of 18.3 photons detected per secondary electron.

Resumen

The new generation of astronomical detectors based on Superconducting Tunnel Junctions (STJs) is capable of detecting photons in a wide range of wavelengths, and, in some cases, even of counting single photons. Since these detectors operate at very low temperature (down to 100 mK), a natural candidate for the readout electronics is the dc-SQUID, a superconducting device that can work as a current preamplifier, reaching very good noise performance. In this paper we present measurements on a homemade dc-SQUID, showing the response of the device to small current pulses, which simulate the real signals from an STJ. An optimal filtering processing of the data is performed, in order to extract from the noisy data the best estimate for the pulse height, which, in a real experiment with single optical photons, would be the parameter that carries the spectroscopic information.

Resumen

The ARIADNE Experiment, utilising a 1-ton dual-phase Liquid Argon Time Projection Chamber (LArTPC), aims to develop and mature optical readout technology for large scale LAr detectors. This paper describes the characterisation, using cosmic muons, of a Timepix3-based camera mounted on the ARIADNE detector. The raw data from the camera are natively 3D and zero suppressed, allowing for straightforward event reconstruction, and a gallery of reconstructed LAr interaction events is presented. Taking advantage of the 1.6 ns time resolution of the readout, the drift velocity of the ionised electrons in LAr was determined to be 1.608 ± 0.005 mm/μs at 0.54 kV/cm. Energy calibration and resolution were determined using through-going muons. The energy resolution was found to be approximately 11% for the presented dataset. A preliminary study of the energy deposition (dEdX) as a function of distance has also been performed for two stopping muon events, and comparison to GEANT4 simulation shows good agreement. The results presented demonstrate the capabilities of this technology, and its application is discussed in the context of the future kiloton-scale dual-phase LAr detectors that will be used in the DUNE programme.

Resumen

LaBr3:Ce crystals have good scintillation properties for X-ray spectroscopy. Initially, they were introduced for radiation imaging in medical physics with either a photomultiplier or SiPM readout, and they found extensive applications in homeland security and gamma-ray astronomy. We used 1″ round LaBr3:Ce crystals to realize compact detectors with the SiPM array readout. The aim was a good energy resolution and a fast time response to detect low-energy X-rays around 100 keV. A natural application was found inside the FAMU experiment, at RIKEN RAL. Its aim is a precise measurement of the proton Zemach radius with impinging muons, to contribute to the solution to the so-called “proton radius puzzle”. Signals to be detected are characteristic X-rays around 130 KeV. A limit for this type of detector, as compared to the ones with a photomultiplier readout, is its poorer timing characteristics due to the large capacity of the SiPM arrays used. In particular, long signal falltimes are a problem in experiments such as FAMU, where a “prompt” background component must be separated from a “delayed” one (after 600 ns) in the signal X-rays to be detected. Dedicated studies were pursued to improve the timing characteristics of the used detectors, starting from hybrid ganging of SiPM cells; then developing a suitable zero pole circuit with a parallel ganging, where an increased overvoltage for the SiPM array was used to compensate for the signal decrease; and finally designing ad hoc electronics to split the 1″ detector’s SiPM array into four quadrants, thus reducing the involved capacitances. The aim was to improve the detectors’ timing characteristics, especially falltime, while keeping a good FWHM energy resolution for low-energy X-ray detection.

Resumen

Les détecteurs gazeux ont démontré, au cours de ces dernières décennies, leur haute performance pour l'imagerie de particules radioactives, atteignant des résolutions spatiales inférieures à 100 µm. Les propriétés scintillantes de certains mélanges gazeux, combinées au gain important des détecteurs gazeux et à l'usage d'une caméra à bas bruit électronique, ont permis d'utiliser la lumière scintillée pour l'imagerie. Cette approche permet d'obtenir une large surface de détection et une haute résolution spatiale tout en réalisant l'imagerie en temps réel à un coût par pixel réduit, avec une faible complexité d'analyse des données. Les principaux objectifs de cette thèse sont d'optimiser la résolution spatiale ainsi que la sensibilité du détecteur, soit par une méthode d'acquisition "événement par événement" avec des temps d'acquisition d'image courts, soit par "intégration" avec des temps d'acquisition longs.Un détecteur Micromegas en verre innovant pour la lecture optique a été développé, tirant parti de la haute résolution spatiale inhérente au détecteur Micromegas.L'adaptabilité du gain du détecteur Micromegas liée au mécanisme d'amplification par avalanche, lui permet de couvrir une large gamme de flux et d'énergies de particules. Durant cette thèse, des mesures d'imagerie ont été réalisées à l'aide de sources avec des niveaux de radioactivité inférieurs à un Becquerel et des énergies de quelques keV, jusqu'à des flux caractéristiques d'un synchrotron et d'une source de spallation, avec des énergies dépassant le MeV.Le rendement lumineux du détecteur a été étudié pour différents mélanges gazeux et pour diverses valeurs de gain sous irradiation aux rayons-X afin d'optimiser la sensibilité du détecteur. L'homogénéité et la précision de la réponse du détecteur ont été caractérisées par radiographie à rayons-X. La Fonction d'Étalement du Point (PSF) du Micromegas à lecture optique a été mesurée à l'aide d'un faisceau de rayons-X parallèles de quelques microns d'épaisseur, générés par le rayonnement synchrotron. Cette mesure a permis de déterminer la résolution spatiale du détecteur pour différentes configurations et d'identifier et de quantifier les effets qui rentrent en jeux. L'impact de la microgrille et des piliers sur la réponse en scintillation du détecteur a également été observé et quantifié.Deux applications ont été choisies afin d'illustrer le potentiel du Micromegas à lecture optique: l'autoradiographie pour la quantification d'échantillons tritiés de très faible activitié et la radiographie neutronique à haute résolution en environnement hautement radioactif.L'autoradiographie et le comptage radioactif de rayonnements beta faiblement énergétiques ont été réalisés avec des échantillons de glucose tritié. Des activités inférieures à un Becquerel ont été mesurées avec précision et simultanément sur un grand nombre d'échantillons tout en assurant une reconstruction précise de leur position. Ce travail valide la possibilité de quantifier la concentration de médicaments anticancéreux à l'échelle de cellules tumorales uniques.Enfin, l'utilisation du Micromegas à lecture optique pour la neutronographie a été démontrée en utilisant une source de spallation produisant des neutrons thermiques à un flux d'environ 10⁸ n. s⁻¹cm⁻ ² mA⁻¹. L'uniformité de la réponse du détecteur a été étudiée, et les effets de la diffusion et du parcours moyen des particules dans le gaz sur la netteté de l'image ont été mesurés et comparés à une simulation. Une résolution spatiale de l'ordre de 400 µm a été obtenue en utilisant une amplification à double étages au sein du détecteur Micromegas
Gaseous detectors have demonstrated, over the past decades, their high performance for imaging radioactive particles, achieving spatial resolutions below 100 µm. The scintillating properties of certain gas mixtures, combined with the significant gain of gaseous detectors and the use of a low-noise camera, have enabled the use of scintillation light for imaging. This approach allows for a large detection surface and high spatial resolution while achieving real-time imaging at a low cost per pixel, with low data analysis complexity. The main objectives of this thesis are to optimize the spatial resolution and sensitivity of the detector, either by an "event-by-event" acquisition method with short image acquisition times or by "integration" with long acquisition times.An innovative glass Micromegas detector for optical readout has been developed, taking advantage of the inherently high spatial resolution of the Micromegas detector. The adaptability of the Micromegas detector's gain, due to the avalanche amplification mechanism, allows it to cover a wide range of particle fluxes and energies. During this thesis, imaging measurements were performed using sources with radioactivity levels below one Becquerel and energies of a few keV, up to fluxes characteristic of a synchrotron and a spallation source, with energies exceeding one MeV.The light yield of the detector was studied for different gas mixtures and various gain values under X-ray irradiation to optimize the detector's sensitivity. The homogeneity and precision of the detector's response were characterized by X-ray radiography. The Point Spread Function (PSF) of the optical readout Micromegas was measured using a parallel X-ray beam a few microns thick, generated by synchrotron radiation. This measurement allowed us to determine the detector's spatial resolution for different configurations and to identify and quantify the effects involved. The impact of the micro-mesh and pillars on the detector's scintillation response was also observed and quantified.Two applications were chosen to illustrate the potential of the optical readout Micromegas: autoradiography, for the quantification of very low-activity tritiated samples and high-resolution neutron radiography in highly radioactive environments.Autoradiography and radioactive counting of low-energy beta radiation were performed with tritiated glucose samples. Activities below one Becquerel were measured accurately and simultaneously on a large number of samples, while ensuring precise reconstruction of their position. This work validates the possibility of quantifying the concentration of anticancer drugs at the scale of single tumor cells.Finally, the use of the optical readout Micromegas for neutron imaging was demonstrated using a spallation source which produces thermal neutrons with a flux of approximately 10⁸ n. s⁻¹cm⁻ ² mA⁻¹. The uniformity of the detector's response was studied, and the effects of the diffusion and the mean free path of particles in the gas on image sharpness were measured and compared to a simulation. A spatial resolution on the order of 400 µm was achieved using double-stage amplification within the Micromegas detector

Resumen

MEMS technology has led to the development of new uncooled infrared imaging detectors. One type of these MEMS detectors consist of arrays of bi-metallic photomechanical pixels that tilt as a function of temperature associated with infrared radiation from the scene. The main advantage of these detectors is the optical readout system that measures the tilt of the beams based on the intensity of the reflected light. This removes the need for electronic readout at each of the sensing elements and reduces the fabrication cost and complexity of sensor design, as well as eliminates the electronic noise at the detector. The optical readout accuracy is sensitive to the uniformity of individual pixels on the array. The hypothesis of the present research is that direct measurements of the height change corresponding to tilt through holographic interferometry will reduce the need for high pixel uniformity. Measurements of displacements for a vacuum packaged detector with nominal responsivity of 2.4nm/K are made with a Linnik interferometer employing the four phase step technique. The interferometer can measure real-time, full-field height variations across the array. In double-exposure mode, the current height map is subtracted from a reference image so that the change in deflection is measured. A software algorithm locates each mirror on the array, extracts the measured deflection at the tip of a mirror, and uses that measurement to form a pixel of a thermogram in real-time. A blackbody target projector with temperature controllable to 0.001K is used to test the thermal resolution of the imaging system. The achieved minimum temperature resolution is better than 0.25K. The double exposure technique removes mirror non-uniformity as a source of noise. A lower than nominal measured responsivity of around 1.5nm/K combined with noise from the measurements made with the interferometric optical readout system limit the potential minimum temperature resolution. Improvements need to be made both in the holographic setup and in the MEMS detector to achieve the target temperature resolution of 0.10K.

Resumen

A room temperature liquid scintillator time projection chamber has the potential to give both ne grained tracking and calorimetry, analogous to liquid argon, only without the cryogenic infrastructure. This type of detector would be invaluable as a cost effective, large volume detector for use in neutrino physics. This motivates the search for candidate liquids with both excellent charge transport properties and optical properties. This work presents results from tests of five dielectric room temperature liquid scintillators; Di isopropyl naphthalene, Phenyl xylyl ethane, Linear alkyl benzene, Mono isopropyl biphenyl, and Mono isopropyl naphthalene, whose charge transport properties are investigated for the first time. The results are also presented from room temperature liquids Tetramethyl pentane, and Cyclopentane, whose optical properties have not previously been investigated. The liquids tested have shown favourable properties, although none of the above liquids has been found to have both charge transport and scintillation light at a suitable level for use in a neutrino detector.

Resumen

Deux technologies de liaison optique ont ete considerees pour la lecture de donnees analogiques dans un environnement fortement radioactif : la modulation directe de la source active (une diode laser ingaasp a emission laterale), ou la modulation externe d'un faisceau lumineux par un modulateur a electro-absorption (cavite fabry-perot en inp, utilisee en mode reflectif). Un modele fonctionnel des prototypes de liaison correspondants aux deux solutions alternatives a ete developpe comme support a leur analyse et optimisation. Des procedures de qualification uniformes (et des outils d'evaluation) ont ete developpes pour permettre de determiner les avantages et inconvenients de chaque solution en vue de l'utilisation dans le detecteur cms. Des prototypes correspondants a differentes architectures ou a differentes classes de composants ont ete evalues et compares. Les resultats experimentaux ont constitue un facteur essentiel sur lequel le choix technologique de la collaboration en faveur de la modulation directe s'est base. La liaison optique a une linearite meilleure que 1% et une gamme dynamique instantanee de l'ordre de 1000 : 1 dans une bande passante de 100 mhz. La puissance dissipee et la tolerance aux radiations sont compatibles avec les specifications du detecteur cms, mais impliquent une re-calibration periodique et un fonctionnement proche du seuil du laser. Une gamme dynamique efficace de 800:1 peut etre maintenue tout au long de la vie du detecteur. Une liaison prototype a ete integree dans une chaine de lecture complete, comportant un serialiseur des donnees au niveau du transmetteur et un digitaliseur des donnees au niveau du recepteur (developpes par d'autres groupes). La performance analogique de la chaine a ete optimisee. Sa fonctionnalite a ete demontree grace a l'emulation des signaux du detecteur. Le modele de la liaison optique est exploite pour analyser la dispersion des parametres attendue des 50 000 canaux. La simulation montecarlo est utilisee pour optimiser les specifications des composants, qui seront fixes dans le cour de l'annee 1999.

Resumen

Gravitational waves are "ripples" in spacetime emitted by massive astrophysical events. Over the past decade, interferometric detectors have been used to measure gravitational waves from the binary mergers of black holes and neutron stars to learn more about such systems; these gravitational waves had frequencies around 100 Hz. Other frequencies of gravitational waves are thought to exist and contain valuable information but are yet to be detected. For example, detecting kilohertz (1–4 kHz) gravitational waves from binary neutron-star mergers could be used to further constrain the neutron-star equation-of-state and better understand exotic states of matter. However, to do so, the sensitivity of current detectors will need to be extended from 100 Hz to the kilohertz regime. The kilohertz sensitivity of current gravitational-wave detectors is limited by quantum noise from the fundamental quantum uncertainties in the state of light inside the detector. This noise can be mitigated by replacing the vacuum fluctuations entering the readout port of the detector with squeezed states. In this thesis, I investigate a new technique to improve kilohertz sensitivity by placing a nondegenerate squeezer inside the detector. This technique, called nondegenerate internal squeezing, improves sensitivity by amplifying the detector's response to the gravitational-wave signal more than it increases the quantum noise. To assess its feasibility, I derive an analytic Hamiltonian model of nondegenerate internal squeezing and calculate its sensitivity and stability as well as analyse its tolerance to the realistic optical losses expected in a future gravitational-wave detector. My model indicates that nondegenerate internal squeezing is stable, robust to detection loss in the readout, and provides a viable alternative to other proposals to improve kilohertz sensitivity. I demonstrate a technique to determine its squeezing threshold and, therefore, the limits of its operation. I find that nondegenerate internal squeezing could feasibly improve the sensitivity of a future detector to 1–4 kHz gravitational waves. I also explore an alternative readout scheme that is promising for broadband 0.1–4 kHz sensitivity.

Resumen

AbstractAn increasing research effort is being carried out to profit from the advantages of photonics not only in long-range telecommunications but also at short distances, to implement board-to-board or chip-to-chip interconnections. In this context, Silicon Photonics emerged as a promising technology, allowing to integrate optical devices in a small silicon chip. However, the integration density made possible by Silicon Photonics revealed the difficulty of operating complex optical architectures in an open-loop way, due to their high sensitivity to fabrication parameters and temperature variations. In this chapter, a low-noise mixed-signal electronic platform implementing feedback control of complex optical architectures is presented. The system exploits the ContactLess Integrated Photonic Probe, a non-invasive detector that senses light in silicon waveguides by measuring their electrical conductance. The CLIPP readout resolution has been maximized thanks to the design of a low-noise multichannel ASIC, achieving an accuracy better than −35 dBm in light monitoring. The feedback loop to stabilize the behaviour of photonic circuits is then closed in the digital domain by a custom mixed-signal electronic platform. Experimental demonstrations of optical communications at high data-rate confirm the effectiveness of the proposed approach.

Resumen

The recent developments of optoelectronics do promote the progress in many other fields. For quantum information processing, we made efforts in manufacturing quantum devices by using optoelectronic techniques. We designed quantum dot embedded nanocavities to serve as efficient quantum emitters; using spectral multiplexing technique, we fabricated a heralded single-photon source, emitting highly pure and speedy single photons; and defects in GaN were observed serving as room temperature quantum random number generators. An entangled photon emitter with visibility of 97% was developed using cascaded second-order nonlinear optical process in PPLN waveguides; and Si3N4 microrings were effectively applied to establish photon entanglers. Readout circuits were optimized to fabricate specific single-photon avalanche detectors, and telecomm-band single-photon avalanche detectors have been improved to 128 × 32 arrays for quantum imaging. A multiplexed quantum memory was explored to simultaneously store 1650 single photons. Opto-electro-mechanical devices were studied or fabricated in order to measure minor quantities in quantum level. These works may shed light on quantum information technology for the future.
