Abstract

CUPID (CUORE Upgrade with Particle ID) is a next-generation ton-scale bolometric experiment that will search for neutrinoless double beta decay. CUPID will have reduced backgrounds compared to CUORE through the ability to distinguish between 0vββ events and α backgrounds by detecting light emissions. To achieve this, it will deploy on the order of 3000 sensors in its detector array, which will introduce additional technical challenges compared to the 1000 sensors currently in CUORE. Using only room-temperature electronics for CUPID would increase the thermal load on the cryostat from the necessary cabling and increase the complexity of the vacuum system. A multiplexed readout with cryogenic electronics is a potentially appealing solution to these challenges. This work will present a characterization of CMOS devices that will guide future cryogenic ASIC design for CUPID readout.
