Description

Cyclotron Radiation Emission Spectroscopy (CRES), a frequency-based method for determining the energy of relativistic electrons, has recently been demonstrated by the Project 8 collaboration. Applying this technique to the tritium endpoint provides a new avenue for measuring the absolute mass-scale of the neutrino. The proof of principle was done in a small waveguide detector using gaseous $^{83\mathrm{m}}$Kr as a source of monoenergetic electrons. As the next step towards a neutrino mass measurement, we have upgraded the existing detector to operate using a molecular tritium source, and to have enhanced radiofrequency properties. Here we discuss the hardware upgrades made to further the capabilities of the CRES technique and the data-analysis challenges faced during the second phase of the Project 8 experiment. We describe our commissioning activities with $^{83\mathrm{m}}$Kr and our progress towards making a measurement of the tritium spectrum.
