The superconducting magnet, cryogenics, and detector systems of the AMS experiment was fully integrated and tested in test beam at CERN during 2009. In Spring 2010 the experiment underwent thermal vacuum tests at ESTEC, where it was operated in conditions simulating those that will pertain in orbit. All elements of the superconducting magnet and cryogenics performed as designed, and equilibrium operation was attained at several values of vacuum case temperature. Details of the tests are presented. A thermal model of the overall cryogenic system was calibrated from those measurements. The model was used to predict the cryogenic lifetime of the experiment, as it would be staged on ISS, to be (28 ± 6) months.

Quantum computers consist of a quantum processor – sets of quantum bits or qubits operating at an extremely low temperature – and a classical electronic controller to read out and control the processor. The machines utilize the unusual properties of matter at extremely small scales – the fact that a qubit, can represent “1” and “0” at the same time, a phenomenon known as superposition. (In traditional digital computing, transistors in silicon chips can exist in one of two states represented in binary by a 1 or 0 not both). Under the right conditions, computations carried out with qubits are equivalent to numerous classical computations performed in parallel, thus greatly enhancing computing power compared to today’s powerful supercomputers and the ability to solve complex problems without the sort of experiments necessary to generate quantum phenomena. this technology is unstable and needs to be stored in a cool environment for faster and more secure operation.In this paper, we discuss the possibility of integrating quantum computers with electronics at deep cryogenic temperatures.

Synchronisation ultra-rapide, mise en forme d’impulsions et commutation efficace sont au cœur des mesures précises. L’objectif de ce projet de thèse est d’apporter le contrôle électronique ultra-rapide aux circuits nanométriques refroidis à des températures de l’ordre du mK. L’opération quantique rapide rapprochera le domaine de l’optique électronique quantique de son homologue photonique avec des applications pour un contrôle électronique rapide et efficace des dispositifs quantiques. Les dispositifs expérimentaux développés au cours de ce projet de thèse sont décrits et testés de manière à esquisser également les possibilités d’intégration dans les technologies quantiques. Dans un premier temps, une impulsion de tension de forme lorentzienne Γ = (76 ± 2) ps est mesurée de manière résolue dans le domaine temporel à des températures cryogéniques. Ensuite, les dérives de phase et d’amplitude sont analysées et optimisé avec le spectre de bruit. Un nouveau dispositif de génération d’impulsions utilisant un générateur de peigne est ensuite décrit et testé. Enfin, un futur réalisation d’une expérience d’interférence quantique par manipulation et détection dans un conducteur quantique est décrite, de même que les défis posés pour les dispositives quantiques à basse température et ses interconnexions
Ultra-fast synchronization, pulse shaping, and efficient switching are at the heart of precise measurements. The aim of this thesis project is to bring ultra-fast electronic control to small nano-metric circuits cooled down to mK temperatures. The fast quantum operation will bring the field of quantum-electronic optics closer to its photoniccounterpart with applications for fast and efficient electronic control in quantum devices. To this end, the experimental setups developed during the thesis project are described and tested in a way to outline also possible device integration for scalable solid-state quantum technology. As a first step, a Lorentzian-shaped voltage pulse with a full width half maximum Γ = (76 ± 2) ps is measured in a time-resolved manner at cryogenic temperatures. Secondly, the phase and amplitude drifts are analyzed and optimized together with the noise spectrum. A new pulse generation setup using a microwave frequency comb generator is then described and tested. Finally, a future realization of a quantum interference experiment by manipulating and detecting electronic pulses in a quantum conductor is described along with challenges for low-temperature quantum hardware and interconnects

Thesis (MScEng (Electrical and Electronic Engineering))--Stellenbosch University, 2008.
This thesis is aimed at testing commercially available CMOS amplifier ICs at 4 K. Super Conducting Electronics (SCE) will also be used to amplify RSFQ signals for easier detection by CMOS technology and better signal-to-noise ratios. The SCE comprises of a Suzuki stack amplifier, a 250 μA JTL and a DC-to-SFQ converter. The Suzuki stack amplifier is simulated in WRSPICE. It is able to amplify an SFQ signal synchronised with an external clock signal. The amplified signal can then be detected by a normal commercially available CMOS amplifier IC. To keep the noise in the signal to a minimum, the commercial amplifier must be be situated as close as possible to the SCE. The amplifier must therefore be able to operate at 4 K. Ten different amplifier ICs were tested and three was found that worked down to 4 K.

The chromogenic properties of tungsten trioxide (WO3) have been studied by photoluminescence spectroscopy at 4.2 K in order to characterize the electronic structure of this material and see how this relates to optical responses during chromogenic coloration. Transition processes between electron energy states are often the cause of optical phenomena and it is important to identify such processes in order to understand the chromogenic coloration of tungsten oxide films. Much research work has been devoted to characterize the physical and chemical mechanisms that are responsible for this coloration and this is of fundamental importance to understand the chromogenic behavior. The latest research shows that oxygen vacancies could play an important role in certain coloration processes, but it is still a matter of debate whether these are important for the overall response. This work aims to identify specific transitions that are related to oxygen vacancies by measuring photoluminescence from films with controlled vacancy content. The main goal of the project was to set up an experiment that could measure photoluminescence at liquid helium temperature. This was done by installing and integrating the components included in this experimental set-up. The films had been prepared prior to this work and were deposited on a nanocrystalline CaF2 substrate, which is a material that has a very large band gap and was therefore expected to fully transparent in the UV range. However it was found that the substrate inelastically scattered the UV excitation light, which produced strong signals that overshadowed the photoluminescence and prevented an effective characterization of the electronic structure in the films. Instead, suggestions were given on how to minimize uncertainty factors and overcome the difficulties met in this work. It was also found that the films attain a lasting blue coloration by exposure to UV light in vacuum, and that this might be due to oxygen being desorbed from the film during experiments in vacuum.

There is an urgent need for characterisation of group V donors in silicon necessary for the development of quantum information processing (QIP) devices, and my PhD work has been contributed towards this objective. In this thesis, three different group V donors were individually studied with scanning tunnelling microscopy (STM) and spectroscopy (STS), combined with DFT calculation and simulated STM images where necessary. Si(001) dosed with phosphine (PH3) at room temperature prior and imaged at 77 K a few minutes later was investigated. Novel phosphine-related features were observed and compared to the room-temperature results [4]. Some features were the same as the room-temperature dissociative products but a new dissociative mechanism was proposed and novel bonding configurations were assigned to the features. A transformation between adsorbates was seen to occur on the surface at 77 K and was attributed to a tip-induced effect. The appearance of the Si-P heterodimer was found to be different at 77 K and room temperature [5] and the reasons for this difference was discussed. Subsurface As and Bi donors below the Si(001):H surface were separately investigated at 77 K. Special sample annealing (flashing) procedures were created for both studies. There were two classes of As features commonly observed while there were three types for Bi. The appearance of the As features related to the As wavefunction informed that the subsurface As donors were electrically neutral but could be reversibly switched to being ionised (positively-charged) by changing the sample bias. Some subsurface As donors can also be negatively-charged, depending on their distances from the surface. DFT calculations were performed and simulated STM images were generated to compare with the experimental data, allowing us to assign the features to As donors at their exact lattice positions. The appearance of the Bi features indicated that the Bi donors were negatively-charged but could be changed to being positively-charged. With the unequal rate of tunnelling in and off the donor energy level, the Bi donors could be switched back to being negatively-charged again. The Bi wavefunction projection was speculated, based on the Bi features.

Pulse tube refrigerators (PTR) are robust, rugged cryocoolers that do not have a moving component at their cold ends. They are often employed for cryogenic cooling of high performance electronics in space applications where reliability is paramount. Miniaturizing these refrigerators has been a subject of intense research interest because of the benefits of minimal size and weight for airborne operation and because miniature coolers would be an enabling technology for other applications. Despite much effort, the extent of possible PTR miniaturization is still uncertain. To partially remedy this, an investigation of the miniaturization of pulse tube refrigerators has been undertaken using several numerical modeling techniques. In support of these models, experiments were performed to determine directional hydrodynamic parameters characteristic of stacked screens of #635 stainless steel and #325 phosphor bronze wire mesh, two fine-mesh porous materials suitable for use in the regenerator and heat exchanger components of miniature PTRs. Complete system level and pulse tube component level CFD models incorporating these parameters were then employed to quantitatively estimate the effects of several phenomena expected to impact the performance of miniature PTRs. These included the presence of preferential flow paths in an annular region near the regenerator wall and increased viscous and thermal boundary layer thicknesses relative to the pulse tube diameter. The effects of tapering or chamfering the junctions between components of dissimilar diameters were also investigated. The results of these models were subsequently applied to produce successively smaller micro-scale PTR models having total volumes as small as 0.141 cc for which sufficient net cooling was predicted to make operation at cryogenic temperatures feasible. The results of this investigation provide design criteria for miniaturized PTRs and establish the feasibility of their operation at frequencies up to 1000 Hz with dimensions roughly an order of magnitude smaller than those that have recently been demonstrated, provided that challenges related to their regenerator fillers and compressors can be addressed.

AbstractElectronic spectroscopy has been instrumental in demonstrating the properties of helium droplets as a cryogenic matrix for molecules. The electronic spectrum of glyoxal, which was one of the first molecules investigated in helium droplets by means of electronic spectroscopy, showed two features that provided convincing evidence that the droplets were superfluid. These were free rotation and the distinct shape of the phonon side band which could be directly assigned to the characteristic dispersion curve of a superfluid. On closer examination, however, details such as increased moments of inertia and a spectral response on the droplet size distribution revealed unexpected features of microsolvation in the superfluid helium. In the course of studying many different molecules, it has become clear that electronic spectroscopy in helium droplets provides insight into the detailed effects of microsolvation. These in turn lead to numerous questions regarding the interaction with the superfluid which are discussed in this chapter. In addition, the influence of microsolvation in helium droplets on van der Waals clusters generated inside helium droplets are discussed. Finally, the effect of helium solvation on unimolecular or bimolecular elementary chemical reactions is evaluated in comparison with corresponding experiments in the gas phase. Particular focus of this article lies on the spectral features related to helium solvation which are not yet fully understood.

During the past several decades, significant performance improvement of microprocessor chips has been obtained mainly by reduction of (transistor) device length scale. Beyond the International Technology Roadmap for Semiconductors (ITRS)-defined 50 nm technology node, the parasitic effects associated with reduction of the feature size (e.g., increase in leakage current) begin to outweigh the favorable effects of increased functionality and speed. One promising route for continued performance improvement is to exploit low temperature operation of microprocessors (also referred to as the temperature scaling [1]). This calls for development of compact, inexpensive, and quiet refrigeration/cryogenics technology, which can be interfaced with electronic components. In this work, we consider thermally driven sorption-assisted refrigeration technology for sub-ambient cooling of high performance electronics. In the past, sorption-based cryocoolers have been successfully developed for cryogenic cooling of sensors in space applications, targeting very low (mW-level) cooling loads. These cryocoolers are quiet, vibration free, reliable since they have no moving parts at high pressure, and therefore offer significant advantages over mechanical refrigeration. In addition, there is no refrigerant-lubricant interaction in sorption-based cryocoolers, which can potentially degrade the evaporator performance. This paper presents a thermodynamics-based analytical framework for the design of sorption compressors for cryogenic cooling of electronics. A sample case study is also presented to illustrate the approach.

This paper presents the developments of high-performance integrated cryogenic power modules, where both driver components and power MOSFETs are integrated in a single package. These modules are designed to be used in liquid nitrogen environment with extreme thermal cycling for the cryogenic power inverters. Compact high-voltage, cryogenic integrated power modules with single power MOSFET that exhibited more than 14x improvement in on-resistance and continuous current-carrying capability exceeding 40A. A multi-power MOSFETs integrated cryogenic power module is then developed in order to further increase the power density and reduce the size and weight of the cryogenic power system. The multi-power MOSFETs module was demonstrated to be able to carry a current above 100A with only a small increase in footprint compared with the single power MOSFET module. At the current level of 100A, the multi-power MOSFETs module has an on-resistance of 5.5mU` at 77K, which is 6 times smaller than that of the single power MOSFET integrated module developed. Two different design approaches taken in the developments of these modules are discussed in this paper.

Abstract Two-beam systems (focused ion beam (FIB) integrated with a scanning electron microscope (SEM)) have enabled site-specific analysis at the nano-scale through in situ “mill and view” capability at high resolution. In addition, a FIB-SEM can be used to cut away a lamella from a bulk sample and thin it for transmission electron microscopy (TEM) imaging. We studied the temperature dependence of FIB milling on compound semiconductors and thin films such as copper that are used in integrated circuits. These materials (GaAs, GaN, InN, etc) react chemically and physically with the gallium in the FIB and change chemical composition and may also change morphology. Copper metallization of IC’s has been difficult to mill without undesirable side effects. FIB milling for analysis of these materials becomes difficult if not impossible. Since temperature can be a big factor in chemical and physical reactions we investigated this and report here the effect of cooling the sample to cryogenic temperatures while milling. In addition, we report on the development of a process to prepare TEM lamellae with FIB entirely in a cryogenic environment.
