The Development of a Preclinical Alpha Irradiation Platform with Versatile Control of Dose, Dose Rate, and Spatiotemporal Irradiation Patterns
Harsh Arya, Joshua Rajan, Varghese Chirayath +7
Objectives. This study develops and validates a vacuum-based alpha irradiation platform to support preclinical radiobiology. We aim to demonstrate precise, independent control over…
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…
