Silicon-germanium (SiGe) is a material that possesses multitude of applications ranging from transistors to electro-optical modulators and quantum dots. The diverse properties SiGe also make it attractive implementations involving superconducting computing. Here, we demonstrate the fabrication transmon bits on layers investigate microwave loss at cryogenic temperatures single photon powers. We ...

A silicon–tungsten prototype calorimeter, for the proposed ALICE LS3-upgarde, was fabricated and tested at CERN-SPS beamline facility in year 2017. The calorimeter designed with help of GEANT4 simulation to perform a high multiplicity density environment optimised energy position resolutions incident up 200 GeV. There were several tests conducted different configurations both laboratory CERN fa...

The Compact Muon Solenoid Collaboration is designing a new high-granularity endcap calorimeter, HGCAL, to be installed later this decade. As part of development work, prototype system was built, with an electromagnetic section consisting 14 double-sided structures, providing 28 sampling layers. Each layer has hexagonal module, where multipad large-area silicon sensor glued between electronics c...

High-energy physics detectors with internal charge multiplication, like Low Gain Avalanche Detectors (LGADs), that will be used for fast timing in the High Luminosity LHC experiments, have to exhibit a significant radiation tolerance. In this context, impact of on highly boron-doped gain layer is particular interest, since due so-called Acceptor Removal Effect (ARE) radiation-induced deactivati...

objective: peripheral arterial disease (pad) is a state characterized by atherosclerotic occlusive disease of lower extremities. diabetes is the main risk factor for pad. material and methods: to assess the prevalence of pad, a cross sectional study was performed on 352 diabetic patients who referred to yazd diabetes research center from 2007 to 2010. vascular assessment was done by measuring t...

introduction: careful planning on health care may prevent the spread of disease and reduce the expense for treatment. regarding the importance of health care in the clinical centers including physiotherapy clinics, this study was designed to investigate the rate of bacterial contamination of electrotherapy’s pads which use in the physiotherapy clinics of semnan university of medical sciences (i...

Abstract Miniaturized, microfabricated microelectromechanical systems-based wafer probes are used here to evaluate different contact pad metallization at low tip forces (<mN) and skate on the on-wafer pads. The target application is force RF for measurements which cause minimal damage both Low enables use of softer, more conductive metallisation. We have studied four thin film metals based t...
