Project 8: Towards measuring the neutrino mass using CRES — •Christine Claessens and Sebastian Böser — Institut für Physik, Johannes Gutenberg-Universität Mainz

The Project 8 collaboration seeks to measure the absolute electron neutrino mass by investigating the endpoint of the tritium beta decay spectrum using a frequency based method. To this purpose the collaboration has recently established Cyclotron Radiation Emission Spectroscopy (CRES) as a new method to determine the energy of relativistic electrons. By trapping electrons from krypton decay in a magnetic field to increase the integration time, the detection of single electrons and the reconstruction of their kinetic energy from the measured cyclotron frequency has successfully been demonstrated (Phys. Rev. Lett. 114, 162501). In this talk the proof of principle prototype design and current results are presented. Furthermore, insight on one of the main challenges for the forthcoming scale-up of the experiment, the development of a fast frequency based trigger, is given.
