Long-term temporal stability of the DarkSide-50 dark matter detector

50 Collaboration, P. Agnes, I. F. M. Albuquerque +142

The stability of a dark matter detector on the timescale of a few years is a key requirement due to the large exposure needed to achieve a competitive sensitivity. It is especially…
