Rn Detection and Mitigation

Presentation

Radon emanation remains a dominant background in rare-event search experiments such as neutrinoless double beta decay and dark matter detection, motivating the development of high-sensitivity assay systems for material screening and detector validation. As a noble gas, radon can outgas of detector materials and circulate within experimental volumes, making it particularly challenging to...

Rn Detection and Mitigation

Presentation

The PICO Collaboration operates bubble chambers to search for WIMP dark matter, leveraging the excellent gamma rejection and long live fractions enabled by operating at a lower degree of superheat than the bubble chambers of the 1960s. Located at the SNOLAB underground laboratory, these detectors use fluorinated target fluids optimized for probing spin-dependent WIMP-proton interactions while...

Rn Detection and Mitigation

Presentation

Despite overwhelming evidence for dark matter in our universe, its true nature remains a mystery. In the search for dark matter, detectors using liquid xenon are currently leading in sensitivity. However, these experiments are increasingly limited by intrinsic detector backgrounds, particularly the emanation of radon from detector materials. To address this challenge, a novel radon mitigation...

29. Demonstration of Efficient Radon Removal by Silver-Zeolite developed for the NEWS-G Dark Matter Experiment

Rn Detection and Mitigation

Presentation

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 compares the radon reduction capabilities of silver-zeolite and the widely used activated charcoal, both at room temperature. We demonstrate that silver-zeolite significantly outperforms activated charcoal by three...
