Real-time event reconstruction in the Project 8 Phase III Free Space CRES Demonstrator — •Florian Thomas and Sebastian Böser for the Project 8 collaboration — PRISMA+ Cluster of Excellence, JGU Mainz

The Project 8 collaboration aims at measuring the absolute neutrino mass with a sensitivity of 40 meV in a tritium endpoint measurement using the recently demonstrated technique of Cyclotron Radiation Emission Spectroscopy (CRES).

In the upcoming Phase III of the experiment CRES will be demonstrated in free space instead of a closed waveguide for the first time. The free space cyclotron radiation emitted by tritium beta decay electrons in a background magnetic field is detected by an array of antennas. For the required sampling frequency a raw data rate of ∼60 GB/s is expected, which quickly exhausts today’s permanent storage capacities. Therefore, most of the event reconstruction has to proceed in real-time. This talk presents beamforming as a proposed reconstruction technique as well as the implementation plans for real-time computing and triggering.
