Abstract:
Cyclotron Radiation Emission Spectroscopy (CRES) is a novel technique for the precise
measurement of relativistic electron energy. This technique is being employed by the Project 8
collaboration for measuring a high-precision tritium beta decay spectrum to perform a frequency-based
measurement of the neutrino mass. In this work, we describe the Project 8 Phase II apparatus, used
for the detection of the CRES signal from the conversion electrons of 83mKr and the first CRES
measurement of the beta-decay spectrum of molecular tritium.
