Description
Radon is one of the most significant terrestrial radioactive backgrounds in multi-ton rare event searches that is continuously emanating from detector components. In order to achieve high detection efficiency for weakly interacting particles such as neutrinos or dark matter, radon contamination must be carefully suppressed. Since radon is a noble atom, it cannot be removed using conventional purification methods such as high temperature getters. Alternative methods, such as distillation towers or charcoal columns have to be employed to either separate radon from other noble elements, or to trap radon atoms long enough for them to decay before leaving the trap. Based on the experience gained from investigating radon reduction using charcoal absorbers charcoal absorbers for the LZ experiment, methods will be discussed for how to reduce radon contamination in G3 experiments.
