Description

To date, all light mass dark matter calorimeters have measured a low energy, non-ionizing background whose rate decreases with time since cooldown. Such bursts have recently also been seen to be the dominant source of parity flipping in superconducting QUBITs. In this talk, we will summarize recent work to understand the source of this background where we correlated the measured burst rate to substrate thickness and to fast neutron exposure.
