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…
Progress on the ALETHEIA project and a new approach to mitigate events overlap
Junhui Liao
The ALETHEIA project aims to search for low-mass dark matter using liquid helium (LHe)-filled time projection chambers (TPCs). While liquid argon and liquid xenon TPCs have been ex…
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…
A novel nuclear recoil calibration for liquid noble gas detectors
Fengbo Gu, Jiangfeng Zhou, Junhui Liao +7
According to many dark matter models, a potential signal registered in a detector would feature a single-scattering nuclear recoil (NR). So, it is crucial to calibrate the detector…
Coating m TPB on a cylindrical detector and studying the sample films being cooled to LN and LHe temperatures
Jiangfeng Zhou, Zebang Ouyang, Junhui Liao +5
ALETHEIA is a newly established dark matter direct detection project that aims at hunting for low-mass WIMPs. TPB is widely implemented in liquid helium and argon experiments to sh…
A low-mass dark matter project, ALETHEIA: A Liquid hElium Time projection cHambEr In dArk matter
Junhui Liao, Yuanning Gao, Zhuo Liang +5
Dark Matter (DM) is one of the most critical questions to be understood and answered in fundamental physics today. Observations with varied astronomical and cosmological technologi…
