TL;DR: The LUX detector as discussed by the authors was designed, constructed, and deployed to mitigate background, both internal and external, for the WIMP search, and is currently in operation at the Davis Campus at the 4850' level of the Sanford Underground Research Facility (SURF) in Lead, SD to directly search for WIMPs.
Journal ArticleDOI
Further test mass charging simulations for astrod i
TL;DR: In this article, the authors present a detailed Monte Carlo simulation of ASTROD I test mass charging due to exposure of the spacecraft to galactic cosmic-ray (GCR) protons and alpha particles ((3)He, (4)He) in the space environment.
Journal ArticleDOI
Investigation of charge management using UV LED device with a torsion pendulum for TianQin
Fangchao Yang,Yanzheng Bai,Wei Hong,Honggang Li,L. Liu,T. J. Sumner,Quanfeng Yang,Yujie Zhao,Zebing Zhou +8 more
TL;DR: In this paper, a charge management system based on ultraviolet (UV) light is developed to reduce the charge-induced noises acting on the test mass in space gravitational experiments such as GP-B, LISA, and TianQin mission.
