Measurements of Neutron-Induced Gamma Ray Background of <sup>100</sup>Mo for CUPID

ORAL

Abstract

CUPID (CUORE with Upgraded Particle IDentification), an update to CUORE (Cryogenic Underground Observatory for Rare Events), is an experiment designed to search for neutrinoless double beta decay using the candidate isotope 100Mo. To estimate the neutron-induced gamma ray background of 100Mo, an experiment was conducted at TUNL (Triangle Universities Nuclear Laboratory) in which neutron beams ranging from 4-8 MeV were targeted at varying samples of 100Mo, 56Fe, and Cu. We present neutron-100Mo gamma production cross sections for decays of interest to the background estimations of CUPID, and set a limit on production of gamma-events within the region of interest.
