Project 8 - The CRES cell design for Phase II


The Project 8 experiment aims to probe the absolute neutrino mass scale down to 40 meV/c^2 by employing the recently demonstrated technique of cyclotron radiation emission spectroscopy (CRES). The energy spectrum of tritium β−decay electrons trapped in a precision magnetic field will be reconstructed from the emitted cyclotron radiation. The first phase of the experiment successfully applied CRES to mono-energetic conversion electrons emitted by 83mKr gas. In the next phase we aim to measure the first continuous electron spectrum and will use molecular tritium. I will discuss the various engineering challenges that had to be addressed to successfully built a CRES cell compatible with tritium operation at cryogenic temperatures and in a precision magnetic field environment.
