Texto completoAccurate temperature measurement is an essential requirement in modern aircraft data acquisition systems. Both thermocouples and Platinum resistance temperature detectors (RTD) are used for this purpose with the latter being both more accurate and more repeatable. To ensure that only the sensor limits the accuracy of a temperature measurement, end-to-end system accuracy forward of the sensor, should be significantly greater than that of the sensor itself. This paper describes a new digital signal processing (DSP) based system for providing precision RTD based temperature measurements with laboratory accuracy in an aviation environment. Advantages of the new system include, true 3-wire RTD measurement, linear temperature output, on-board ultra-precision resistance standards and transparent dynamic calibration.

Texto completoThe observation of relative atmospheric absorption (in dB) using Riometers (Relative Ionospheric Opacity Meter) is a well established method. However, the measurement of atmospheric absorption as a noise temperature with absolutely calibrated radars has rarely been realized. This work demonstrates the possibilities to perform an absolute radar calibration for standard SKiYMET meteor radars. The measured QDC (Quiet Day Curve) and the comparison to a reference QDC illustrates the capability to quantify the effect of the antenna pattern. The achieved accuracy for a QDC is approximately 600 K. The high stability of the observation during normal meteor mode allows also to investigate the ionospheric response caused by the coupling of the solar activity.
Lombardo, Simona. "A flux calibration device for Integral Field Spectrographs". Doctoral thesis, Humboldt-Universität zu Berlin, 2017. http://dx.doi.org/10.18452/18054.
Texto completoSNe Ia can be used as standard candles to measure the dark energy equation of state parameter, w. Having observed a good number of these objects, current studies are limited by systematic uncertainties, among which relative (color) flux calibration is dominating. This work presents a way to solve, or at least limit, the problem with the SNIFS Calibration Apparatus (SCALA). SCALA's goal is to provide high precision calibration for the “telescope+ SNIFS” system and refine the primary standard star network, to eliminate the uncertainties due to the knowledge of their models. SCALA produces 18 quasi-parallel and collimated monochromatic (and wavelength tunable) beams with opening angles of 1 degree. The combination of these beams allows us to achieve an illumination of the focal plane of the University of Hawaii 88 inches telescope (UH 88), that is flat to within 1%. SCALA was commissioned in 2014 and fully deployed in 2015. In the in-situ set up, one of the SCALA beams is constantly monitored by a photodiode (calibrated against a NIST-calibrated photodiode), which is used as flux standard to transfer the NIST-calibration to the telescope+instrument first, and the standard star spectra afterwards. We measure the overall wavelength trend of the illumination from SCALA with a precision better than 1%, by moving another of these calibrated photodiodes from beam to beam. We can hence measure relative trasmissivity curves for each SCALA beam. Therefore, we can produce throughput curves of the SNIFS+UH 88 system. The measured systematics affecting our results sum to errors smaller than 0.7%. The next step would be to compare the calibration of the system achieved with SCALA with the traditional calibration obtained by observing standard stars.

Texto completoSCALA is a calibration system for the SuperNova Integral Field Spectrograph (SNIFS), which is mounted to the University Hawaii 2.2 m telescope. The aim of SCALA is to reduce the uncertainties on the flux calibration for luminosity distance measures. It therefore allows the reduction of the uncertainties on the time variability of the Dark Energy. SCALA enables us to calibrate SNIFS relative to a laboratory standard, which is realized by a photodiode, that is itself calibrated against a primary standard at NIST (National Institute of Standards and Technology). To transfer the calibration, we illuminate both the photodiode and SNIFS with a wavelength-tunable, monochromatic light source. This calibration allows us to compare the laboratory system to the astronomical CALSPEC system. The first results were presented in dissertation of Simona Lombardo. We have now identified several sources of systematic uncertainty that were affecting our measurements. After correcting for these effects, the wavelength-dependency of the calibration by SCALA agrees with the CALSPEC system in the wavelength range 450 nm to 900 nm (within our uncertainties of 1.5%). In the future, the identified sources of systematic uncertainty could be reduced through improvements to the setup. This would allow comparisons to the CALSPEC system with uncertainties < 1 % and a wavelength range extension down to 350nm.

Texto completoThe initial part of the thesis contains the description of the method for electromagnetic calorimeter calibration, correcting for the Data-MC discrepancy in the development of the electromagnetic showers in the calorimeter. The method improves electron identification and reduces the associated systematic uncertainty.The major part of the thesis is dedicated to the precise measurement of the W boson transverse spectrum using the data, collected by the ATLAS experiment at the energies of 5 and 13 TeV during two special low pile-up runs in 2017 and 2018. The motivation for the precise measurement of the W boson transverse spectrum is twofold. First, it serves as a test for the theoretical predictions obtained within the Standard Model and allows to benchmark the performance of the Monte-Carlo (MC) generators. The second reason is because the W pT spectrum is an input component for the measurement of the W boson mass which is a Standard Model parameter. The use of low pile-up data allows to significantly reduce the hadronic recoil systematic uncertainty improving the precision of the spectrum measurement. The thesis describes the methodology of the W boson pT spectrum measurement as well as the imposed calibrations, corrections and the associated uncertainties. The final result is obtained from the measured hadronic recoil using an unfolding procedure and is compared to the theoretical predictions obtained with different Monte-Carlo generators. An alternative method for the hadronic recoil reconstruction with the use of deep neural networks is proposed in the thesis. The method is shown to improve the resolution of the measured hadronic recoil by about 10% in the most relevant region of low pT. The observables obtained using approach improve the sensitivity to the mass of the W boson

O objetivo desta Tese de Doutorado foi avaliar o método de adição de padrão interno empregando técnicas espectroscópicas. Inicialmente o método de adição de padrão interno foi aplicado no modo convencional na determinação de Ca e Mg em amostras biodiesel e urina por espectrometria de absorção atômica em chama de alta resolução e fonte contínua e na determinação de ureia em urina por espectroscopia Raman. Para fins comparativos, todas as amostras e materiais certificados foram também analisados pelos métodos de calibração externa, adição de padrão e padronização interna. Nitrato, Sr e Mn foram selecionados como padrões internos para ureia, Ca e Mg, respectivamente. Para avaliar a exatidão do método na determinação de Ca e Mg foram analisados nove materiais de referência certificados (CRM) e os resultados obtidos foram concordantes a 95% de confiança com os valores certificados (teste t). Para ureia a exatidão foi avaliada por meio de comparação dos resultados obtidos pelo método de adição de padrão interno e por um método de referência. Todos os resultados obtidos foram concordantes entre si (teste t pareado) ao nível de 95% de confiança. A exatidão do método também foi checada por meio de testes de adição e recuperação: Ca (93 – 119%), Mg (100 – 116%) e ureia (99 – 105%). A desvantagem do método de adição de padrão interno convencional foi o volume total de amostra utilizado, a quantidade de soluções analíticas empregadas e a baixa frequência analítica. No entanto, este problemas foram solucionados com o desenvolvimento de sistemas em fluxo e pelo uso de um gradiente de concentração. O método de adição de padrão interno por gradiente de concentração em fluxo foi avaliado na determinação de Na e K em amostras de biodiesel e urina por espectrometria de emissão atômica em chama e na determinação de etanol em gasolina por espectroscopia Raman. Lítio foi empregado como padrão interno para Na e K, e acetona foi utilizada como padrão interno para etanol. A exatidão do método na determinação de Na e K foi avaliada por meio da análise de cinco CRMs, e os resultados obtidos para Na foram concordantes a 95% de confiança com os valores certificados (teste t), para K os resultados apresentaram valores subestimados ao longo do trabalho (em torno de 80% de recuperação). Para determinação de etanol em gasolina a exatidão foi avaliada por meio da comparação dos resultados obtidos pelo método proposto e pelo método de referência, e todos os resultados obtidos foram concordantes entre si (teste t pareado) ao nível de 95% de confiança. A exatidão do método de adição de padrão interno por gradiente de concentração em fluxo também foi avaliada por meio de testes de adição e recuperação: Na (94 – 110%), K (73 – 86%) e etanol (99 – 104%). Os resultados obtidos utilizando o método de adição de padrão interno (convencional e em fluxo) em todas as aplicações apresentaram precisão e exatidão melhores ou comparáveis aos métodos de adição de padrão, padronização interna e calibração externa, mostrando ser uma estratégia de calibração eficiente para técnicas espectroscópicas.
The aim of this Doctoral Thesis was to evaluation of the internal standard addition method employing spectroscopic techniques. Initially, traditional standard addition method was applied for Ca and Mg determination in biodiesel and urine samples by high-resolution continuum source flame atomic absorption spectrometry and for urea determination in urine samples by Raman spectroscopy. For comparison purposes, all samples and certified materials were also analyzed by external calibration, standard addition and internal standardization methods. Nitrate, Sr and Mn were selected as internal standards for urea, Ca and Mg, respectively. In order to verify the accuracy for Ca and Mg determination were analyzed nine certified reference materials (CRM), the results were in agreement with certified values at the 95% confidence level (t-test). For urea, the accuracy was evaluated by comparison of the results obtained by internal standard addition and a reference method. All results were in agreement at 95% confidence level (paired t-test) with each other. The accuracy was also checked by addition and recovery tests: Ca (93 - 119%), Mg (100 - 116%) and urea (99 - 105%). The drawbacks of traditional internal standard addition were the total volume of sample used, the amount of analytical solutions employed and the lower sample throughput. However, these problems were solved with the development of flow systems and the use of a concentration gradient. The internal standard addition by flow gradient concentration was evaluated for Na and K determination in biodiesel and urine samples by flame emission atomic spectrometry and for ethanol determination in gasoline by Raman spectroscopy. Lithium was selected as internal standard for Na and K, and acetone was selected as internal standard for ethanol. The accuracy of the method for Na and K determination was evaluated by five CRMs analysis, and the results obtained for Na were in agreement with certified values at the 95% confidence level (t-test), for K the results presented underestimated values throughout the study (around 80% recovery). The accuracy for ethanol determination in gasoline was evaluated comparing the results obtained by the proposed method with the reference method. All results were in agreement at 95% confidence level (paired t-test) with each other. The accuracy of internal standard addition by flow gradient concertation method was also evaluated by addition and recovery tests: Na (94 - 110%), K (73 - 86%) e ethanol (99 - 104%). The results obtained by internal standard addition (traditional and flow modes) for all applications showed accuracy and precision better or comparable with traditional calibration methods (standard addition, internal standardization and external calibration), revealing to be an efficient calibration strategy for spectroscopic techniques.

Texto completoThe first part of this thesis is dedicated to the extraction of jet energy scale corrections for the CMS experiment at the LHC. Various extraction methods are described, with a particular interest on corrections extraction using photon + jets events. These corrections are necessary for all analyses using jets and are already used by the whole collaboration. The second part presents the searches for new physics beyond the Standard Model. Many models of new physics predict new particles with enhanced coupling to the top quark, which can show up as resonances in the top-antitop invariant mass spectrum. Two separate analyses are described in this thesis, one dedicated to the search of spin 1 resonances and one dedicated to the search of spin 0 resonances, where interference effects with the Standard Model production are taken into account

Texto completoCette thèse présente une mesure de la section efficace de production de jets associés à un boson Z dans les collisions proton-proton du Grand Collisionneur de Hadron (LHC) situé au CERN, avec des énergies dans le centre de masse de 8 TeV et 13 TeV, respectivement pour les années 2012 et 2015. Les données utilisées pour cette analyse ont été collectées par le détecteur Compact Muon Solenoid (CMS). Elles constituent des échantillons de luminosités intégrées de 19.6 fb⁻¹ et 2.25 fb⁻¹, respectivement pour 2012 et 2015. Nous mesurons la section efficace différentielle en fonction de la multiplicité de jets, de l’impulsion transverse et de la rapidité des jets, et en fonction de la somme scalaire des impulsions transverses des jets. La corrélation entre les rapidités du boson Z et des jets est aussi mesurée et bénéficie de la large statistique prise en 2012. Toutes les distributions d’observables mesurées sont obtenues après corrections pour les effets détecteurs et les résultats des canaux de désintégration muonique et électronique du boson Z sont combinés. Tenant compte des incertitudes statistiques et systématiques, les mesures sont comparées à différentes prédictions théoriques ayant différents niveaux de précision. Les prédictions sont obtenues de MADGRAPH 5, SHERPA 2 (pour l’analyse à 8 TeV uniquement), MADGRAPH_AMC@NLO, et un modèle fixé au NNLO (pour l’analyse à 13 TeV uniquement). Par ces mesures de précisions, et en particulier celle de la corrélation de rapidités, nous avons acquis une compréhension plus approfondie de la chromodynamique quantique dans son régime perturbatif. Grâce à la plus haute énergie jamais atteinte en laboratoire, et à la grande statistique disponible, nous avons sondé avec précision des endroits de l’espace des phases jusque là inaccessibles.Dans cette thèse, les corrections et la calibration de l’énergie des jets pour le haut niveau de sélection de CMS est également présentée. Durant la période de 2012 à 2015, le LHC a été amélioré, non seulement l’énergie dans le centre de masse a augmenté, mais la luminosité instantanée a aussi été amplifiée. L’écart temporelle entre deux paquets de particules dans les faisceaux du LHC a été réduite. L’une des conséquences est que l’impulsion reconstruite pour les jets produits lors d’un croisement de faisceau à une contribution significative venant des multiples interactions ayant lieux lors du croisement des paquets. Une approche technique dédiée a été développée pour corriger l'impulsion des jets. Les corrections obtenues ont été calibrées aux données prises en 2015 et 2016.

Texto completoThis thesis firstly describes a measurement of the b-jet tagging efficiency with a tag-and-probe method using data recorded by the ATLAS detector in 2015 and 2016. The efficiency measurement method, the object selection, the event and probe jet selection, the evaluation of the statistical and systematic uncertainties, and the final results are discussed. The b-tagging efficiencies have been measured as a function of the jet transverse momentum, pseudorapidity and of the average number of pile-up collisions. The efficiencies measured in data have been compared to those predicted from simulation, and simulation-to-data efficiency scale factors have been determined. The efficiency scale factors are close to unity, with total uncertainty ranging between 2% and 12%. The second part of this thesis focuses on the search for the decays of the Standard Model (SM) Higgs boson to bottom quarks in the associated production mode with vector bosons. Two measurements have been performed and are described here: the first one is based on of 13 TeV pp collisions recorded by ATLAS during the LHC Run-2 until 2016; the second one includes the additional of 13 TeV pp collisions recorded in 2017. For the study based on of data, the object reconstruction, event selection and classification, the techniques to discriminate the signal from the background, the main background and their modelling, the signal properties and the interpretation of results are discussed. For the study based on data, the main difference from the previous study are highlighted. Both results provide a strong evidence of the process, with statistical significances of 3.5 and 4.9 standard deviations, respectively. The signal strength, defined as the ratio between the measured cross section times branching ratio and the SM prediction, is measured with the 2015–2017 dataset to be , indicating good agreement with the SM. The combination of the results based on of 13 TeV collisions with the results of the same analysis performed on data collected at lower (7 and 8 TeV) centre-of-mass energies in 2011 and 2012, and witht those of the searches of decays in other Higgs boson production modes (vector-boson fusion, associated production with a top-quark pair) have led to the observation of the decay with a significance of 5.4 standard deviations, and to a measurement of the signal strength . A combination of the results of the results based on of 13 TeV collisions with the results of searches for the same production mode on the same amount of data in the diphoton and ZZ∗ → 4l Higgs boson final states has led to the observation of VH production with a significance of 5.3 standard deviations, and to a measurement of the signal strength , in good agreement with the SM

Texto completoDiscovery of Higgs boson at LHC in 2012 is the most recent confirmation of the validity of Standard Model, theory describing elementary particles and their interactions. Many analysis now target the extraction of properties of the newly-discovered particle. A direct measurement in the ATLAS experiment of the top Yukawa coupling, one of these properties, is targeted in this work through ttH process. This coupling is of particular interest because of its strong sensitivity to New Physics. The first part of the work is about the automation of the calibration of the hadronic tile calorimeter of the ATLAS detector. A detailed description of the laser system used for a regular calibration of the calorimeter is done as well as of the calibration itself. Then more details on the algorithm written for the automation of the calibration are given. The final goal of this algorithm is to ease and fasten the calibration of channels with gain variation. The second part is dedicated to the search for ttH process through multilepton final states with emphasis on final state with two same-sign leptons, at least four jets and at least 1 b-tagged jet. Estimation of reducible backgrounds and statistical treatment of the analysis are detailed. A first version of the analysis with 13.2f b −1 , corresponding to 2015 and mid-2016 LHC data, ends with a final precision too low to extract any conclusion on the tt̄H process. In a second version of the analysis, improvements are made using multivariate analysis and adding more signal regions. The results from the multilepton analysis is combined with results from other ttH analysis, targeting other Higgs decays, to attain a final observed sentivity of 4.2σ. Thus an evidence for ttH production can be claimed from this combination. The final results give good agreement with Standard Model prediction

Texto completoThe Standard Model of particle physics is used to describe the behavior of the particles and their interactions. One of them, the top quark, is the heaviest elementary particle. This property gives it a favored role in the New Physics theories, it could interact preferentially with new particles predicted by these models.This thesis was performed using the ATLAS detector at LHC. The first part of this work was on the calibration of the ATLAS hadronic calorimeter, part of the detector which is used to measure the energy of the hadrons produced during the collisions. The hadronic calorimeter is calibrated with a laser system, which sends pulses to the 9852 calorimeter’s channels. With this study, drifting channels were corrected by applying correction factors on the data.The second part of this thesis was dedicated to the search of events with two same-sign top quarks. The topology with a same-sign dilepton pair is used to have a clear signature and show only a few Standard Model backgroud processes. Two versions of this analysis are discussed : one of them with a part of the data collected in 2012 and the other one, with a lot of optimizations and with the complete dataset of 2012. These optimizations permits to improve the sensitivity of the signal by a factor 3. Without any excess observed in the data events, it is possible to calculate a limit on the cross section of the same-sign top quarks pair and interpreted in the case of two effective models

Texto completoAt present where nanotechnology applications are growing fast and nano products spreading worldwide, measurement accuracy at nanometer scale becomes an essential challenge to improve the performance and the quality of products integrating nano. To meet the specific needs in the field of dimensional nanometrology, LNE (French metrology institute) integrally designed a metrological Atomic Force Microscope (mAFM). Its main objective is to ensure the traceability of nanoscale measurements to the meter as defined by the International System of Units (SI). The mAFM uses four differential interferometers which measure the tip to sample relative position. This instrument will be devoted to the calibration of transfer standards commonly used in scanning probe microscopy (SPM) and scanning electron microscopy (SEM). During this process, a measurement uncertainty is evaluated to determine a confidence level of the calibration realized by the mAFM. This uncertainty is usually evaluated thanks to experimental measurements which determine the impact of some error sources which degrade measurements at the nanoscale. For other components, their evaluation can be more complex and sometimes impossible to estimate experimentally. To overcome this difficulty, the thesis work consisted in the development of a numerical model called "Virtual AFM". It allows producting the measurement uncertainty of the LNE's mAFM and to identify the critical components by using statistic tools such as Monte Carlo Method (MCM), Morris' design and Sobol' indices. The model uses essentially oriented-object programming to take into account a maximum of interactions from about 140 input quantities. It allowed integrating components previously neglected or overestimated due to a lack of information
