Description
The Project 8 experiment is a next generation neutrino mass experiment that aims to measure the absolute neutrino mass with a sensitivity of 40 meV by measuring the electron energy spectrum close to the tritium beta endpoint. To overcome statistical and systematic limitations of current direct neutrino mass experiments, Project 8 uses the new detection method of cyclotron radiation emission spectroscopy (CRES) and atomic tritium instead of molecular. In former demonstrators the Project 8 collaboration demonstrated the CRES method on krypton or molecular tritium in the closed volume of a waveguide and presented the first neutrino mass upper limits using the CRES technique.
To demonstrate the scaling of the CRES technique, the free space CRES demonstrator which uses an array of antennas to detect cyclotron radiation in free space, is being developed. Choices in the design process should be justified by the effect on the neutrino mass sensitivity. In this contribution we will introduce the method used to calculate neutrino mass sensitivities in Project 8 and apply it to the free space CRES demonstrator.
