Search for Low-Energy Events with CUORE-0 and CUORE
ORAL
Abstract
CUORE-0 is a cryogenic detector that uses an array of tellurium dioxide bolometers with the primary physics goal of searching for neutrinoless double-beta decay of $^{130}$Te. The detector consists of 52 $^{\mathrm{nat}}$TeO$_{2}$ crystal bolometers, which amounts to a total $^{130}$Te mass of 11kg, held in a ultra-pure copper frame. It was assembled using new low-background techniques developed for CUORE. The first results on the search for neutrinoless double-beta decay with CUORE-0 combined with Cuoricinio, a predecessor to CUORE-0, set the most stringent limit on the half-life of $^{130}$Te. Successful background mitigation, along with continuous data acquisition make CUORE-0 also suitable for other low-energy, rare event searches such as dark matter. I will discuss the status of the low-energy event search with CUORE-0 and prospects for CUORE. CUORE is in the final stages of construction and scheduled to begin data-taking in late 2015.
