Determining the neutrino mass with Project8: Improving track reconstruction — •Michael Gödel, Christine Claessens, and Sebastian Böser — Johannes Gutenberg Universität Mainz, Institut für Physik, Deutschland

Project 8 aims to measure the absolute neutrino mass scale from the end point distortion of the tritium beta decay spectrum by using Cyclotron Radiation Emission Spectroscopy (CRES). In this approach the electrons are trapped in a magnetic field causing them to emit cyclotron radiation. By recording the frequency of the resulting radio frequency signal in which electrons will appear as lines in a spectrogram, the electron's energy can be reconstructed. The electron signatures can be extracted by applying image processing techniques. In this contribution a short introduction into the experiment is given. A comparison of different event reconstruction methods is presented by taking a look at their characteristic properties and performances.
