Electric Field Optimization of High-Voltage Vacuum Feedthroughs
Lin Si, Evan Angelico, Giorgio Gratta
We report on the optimization of high voltage vacuum feedthroughs meant to minimize the electric field on the vacuum side of the device. We find that commercial feedthroughs genera…
A flexible test facility for liquid xenon detector development
Evan Angelico, Jacopo Dalmasson, Ralph DeVoe +6
As liquid xenon time projection chambers scale to ever-larger sizes, so too do the engineering challenges they pose. We describe a large, flexible, multipurpose test facility capab…
Development of High-Sensitivity Radon Emanation Measurement Systems with Surface Treatment Optimization
Yuan Wu, Lin Si, Zhicheng Qian +7
Radon and its progenies are significant sources of background in rare event detection experiments, including dark matter searches like the PandaX-4T experiment and other rare decay…
A Novel Low-Background Photomultiplier Tube Developed for Xenon Based Detectors
Youhui Yun, Zhizhen Zhou, Baoguo An +22
Photomultiplier tubes (PMTs) are essential in xenon detectors like PandaX, LZ, and XENON experiments for dark matter searches and neutrino properties measurement. To minimize PMT-i…
PandaX-xT: a Multi-ten-tonne Liquid Xenon Observatory at the China Jinping Underground Laboratory
PandaX Collaboration, Abdusalam Abdukerim, Zihao Bo +90
We propose a major upgrade to the existing PandaX-4T experiment in the China Jinping Underground Laboratory. The new experiment, PandaX-xT, will be a multi-ten-tonne liquid xenon,…
Design and Experimental Application of a Radon Diffusion Chamber for Determining Diffusion Coefficients in Membrane Materials
Liang-Yu Wu, Lin Si, Yuan Wu +13
In recent years, the issue of radon emanation and diffusion has become a critical concern for rare decay experiments, such as JUNO and PandaX-4T. This paper introduces a detector d…
