Description

For many current detectors aimed at rare-event searches, radon is a dominating source of background. These experiments can strongly benefit from the reduction of ${}^{222}\mathrm{Rn}$ that is released by metallic surfaces within the setup. A new radon mitigation strategy employing thin surface coatings has been studied and significant reduction factors of the ${}^{220}\mathrm{Rn}$ and ${}^{222}\mathrm{Rn}$ emanation rates were found. Results for different deposition techniques such as sputtering, plasma deposition and electrodeposition will be summarized and outlooks on possible leads for further developments will be given.
