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…
Ferromagnetic broadband sensing of axionlike dark matter
Chenhao Peng, Dmitry Budker, Yuanning Gao +6
Levitated particles have demonstrated ultrahigh sensitivity to magnetic fields and accelerations owing to their extremely low dissipation. Such systems have strong potential for fu…
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…
