Improving the light collection efficiency of silicon photomultipliers through the use of metalenses
A. A. Loya Villalpando, J. Martin-Albo, W. T. Chen +4
Metalenses are optical devices that implement nanostructures as phase shifters to focus incident light. Their compactness and simple fabrication make them a potential cost-effectiv…
Observation and applications of single-electron charge signals in the XENON100 experiment
E. Aprile, M. Alfonsi, K. Arisaka +77
The XENON100 dark matter experiment uses liquid xenon in a time projection chamber (TPC) to measure xenon nuclear recoils resulting from the scattering of dark matter Weakly Intera…
Hybrid Multi Micropattern Gaseous Photomultiplier for detection of liquid-xenon scintillation
Samuel Duval, Lior Arazi, Amos Breskin +19
Gaseous PhotoMultipliers (GPM) are a very promising alternative of vacuum PMTs especially for large-size noble-liquid detectors in the field of Functional Nuclear Medical Imaging a…
Measurement of the transverse diffusion coefficient of charge in liquid xenon
W. -T. Chen, H. Carduner, J. -P. Cussonneau +11
Liquid xenon (LXe) is a very attractive material as a detection medium for ionization detectors due to its high density, high atomic number, and low energy required to produce elec…
A liquid xenon TPC for a medical imaging Compton telescope
T. Oger, W-T. Chen, J-P. Cussonneau +10
A new technique for medical imaging, "3γ imaging", is studied by our group at SUBATECH for few years. A small liquid xenon time projection chamber prototype has been built in order…
Radiation hardness qualification of PbWO4 scintillation crystals for the CMS Electromagnetic Calorimeter
The CMS Electromagnetic Calorimeter Group, P. Adzic, N. Almeida +267
Ensuring the radiation hardness of PbWO4 crystals was one of the main priorities during the construction of the electromagnetic calorimeter of the CMS experiment at CERN. The produ…
