Description
Radon remains one of the dominant backgrounds limiting the sensitivity of rare-event physics experiments searching for dark matter, neutrinoless double beta decay, and other exotic phenomena. The radioactive decay of radon progeny can produce signals that mimic the interactions of interest, making the detection and control of radon crucial for achieving the sensitivity required by next-generation experiments.
This presentation will outline recent results on radon assay and suppression using the Detecting Radon Emanating and Mitigating Radon (DREAMR) Facility at the Australian National University. Radon suppression results using standard and novel filtration materials, as well as surface electroplating will be presented, as well as preliminary radon emanation assay measurements from DREAMR. Given the high radon background at the Stawell Underground Physics Laboratory (SUPL), activities to understand and mitigate this radon background at SUPL will also be reported. Finally, initial activities from a new international benchmarking and intercomparison program to allow standardised comparisons between various radon detection, assay and mitigation technologies will be discussed. This coordinated technical program brings together radon experts from major low-background experiments and underground laboratories to support the sensitivity goals of future experiments.
