Simulation of the electron escape ratio for keV alpha-particle ionization tracks in liquid helium
Zihuai Hu, Junhui Liao, Zhuo Liang +6
The electron escape ratio for 5.3 MeV alpha-particle ionization tracks in liquid helium under varying external electric fields has been measured in several experiments. However, to…

Characterization of FBK NUV-HD-Cryo SiPMs near LHe temperature
Fengbo Gu, Junhui Liao, Jiangfeng Zhou +13
Five FBK ``NUV-HD-Cryo'' SiPMs have been characterized at 7 K and 10 K, with 405 nm and 530 nm LED light, respectively. The dark count rate (DCR) was measured to be 1 Hz for…

Conceptual design and progress of transmitting MV DC HV into 4 K LHe detectors
Zhuo Liang, Fengbo Gu, Jiangfeng Zhou +12
A dual-phase TPC (Time Projection Chamber) is more advanced in characterizing an event than a single-phase one because it can, in principle, reconstruct the 3D (X-Y-Z) image of the…
