Characterizing Waveguide Antennas for Project 8

The Project 8 collaboration is pioneering the technique of Cyclotron Radiation Emission Spectroscopy (CRES) and aims to probe the absolute mass scale of the electron antineutrino down to 40 meV. One strategy towards this goal utilizes a ring of waveguide antennas surrounding a detector volume of interest. The antennas measure CRES events around the endpoint region of the beta decay of atomic tritium. Benchtop measurements are performed at room temperature using a full ring of antennas and a source of synthetic CRES signatures. These measurements help characterize a scalable detector prototype and serve to benchmark the technological requirements for both antenna and cavity-based approaches to CRES detectors. In this talk, I will present the status of the measurements to characterize the antenna-based approach for the Project 8 neutrino mass experiment.
