The development of the new HE-6 CRES SiPM Beta Monitor

Abstract: 

He-6 CRES aims to look for chirality-flipping coupling by measuring the Fierz interference term. This is done by sending beta decays from He-6 and Ne-19 to a magnetic trap and analyzing the frequency of the resulting cyclotron motion over time. Since the data is taken at different slices along the beta spectrum, the rates of beta decay must be normalized for all data, hence the need for a beta monitor. The development of the new He-6 CRES beta monitor focused on resolving the weaknesses of the previous beta monitor, using a design centered around scintillators in coincidence, temperature-correcting power supplies with a unique bias for each SiPM, and a housing that couples directly to the vacuum system.
