Demonstration of Efficient Radon Removal by Silver-Zeolite in a Dark Matter Detector
Daniel Durnford, Yuqi Deng, Carter Garrah +6
We present the performance of an efficient radon trap using silver-zeolite Ag-ETS-10, measured with a spherical proportional counter filled with an argon/methane mixture. Our study…

The ionization yield in a methane-filled spherical proportional counter
M. M. Arora, L. Balogh, C. Beaufort +40
Spherical proportional counters (SPCs) are gaseous particle detectors sensitive to single ionization electrons in their target media, with large detector volumes and low background…
