Studies on Radioactive Background Mitigation for the PICO-500 Dark Matter Search Experiment
DownloadFall 2024
The PICO-500 dark matter search experiment features the next-generation bubble chamber detector designed by the PICO collaboration. The sensitivity and live-time of ultra-low background detectors, such as PICO-500, are crucially dependent on the radio-pure materials used in the construction. The...

Bubble chambers filled with fluorocarbons are a world-leading technology to search for nuclear recoils produced by spin-dependent WIMP dark matter particles. In this work, a novel bubble chamber using 28 ± 1 ml of the fluorocarbon C5F12 as target material is investigated. This superheated...
