Charge Transport and Multiplication in Lateral Amorphous Selenium Devices Under Cryogenic Conditions
M. Rooks, S. Abbaszadeh, J. Asaadi +6
Cryogenic photon sensing for high-energy physics motivates photosensor technologies that combine large-area scalability with internal gain and stable operation at low temperature.…
Cryogenic UV detection using stress-engineered zero-bias ZnO-thin film based Piezo-Photonic detector
P. Sau, N. Hancock, I. Tzoka +6
We demonstrate a zero-bias ultraviolet (UV) detector using zinc oxide (ZnO) thin films as the active semiconductor layer, specifically for application in cryogenic conditions. The…
Characterization of Lateral Amorphous Selenium Photodetectors for Low-Photon and VUV Detection at Cryogenic Temperatures
M. Rooks, S. Abbaszadeh, J. Asaadi +7
The performance of amorphous selenium (a-Se) as a cryogenic photodetector material is evaluated through a series of experiments using laterally structured devices operated in a cus…
Opportunities and challenges to study solar neutrinos with a Q-Pix pixel readout
M. Ã. GarcÃa-Peris, G. Ruiz, S. Kubota +24
The study of solar neutrinos presents significant opportunities in astrophysics, nuclear physics, and particle physics. However, the low-energy nature of these neutrinos introduces…
Temperature Dependent Optical Response Of High- Tc Yba2cu3o7-δ (Ybco) Thin Films
Vivek Khichar, V. A. Chirayath, Jonathan Asaadi +5
We report on the temperature-dependent optical response of thin films of YBa2Cu3O7-δ (YBCO) in the visible spectral range under cryogenic conditions. Specifically, we observe an i…
First operation of a multi-channel Q-Pix prototype: measuring transverse electron diffusion in a gas time projection chamber
Nora Hoch, Olivia Seidel, Varghese A. Chirayath +19
We report measurements of the transverse diffusion of electrons in P-10 gas (90% Ar, 10% CH4) in a laboratory-scale time projection chamber (TPC) utilizing a novel pixelated signal…
