Calibration Techniques for the Project 8 Neutrino Mass Experiment
Abstract
The goal of the Project 8 experiment is to measure the mass of the electron neutrino by studying the tritium beta-decay spectrum. To improve upon the current neutrino-mass limits we will use a new type of electron energy spectroscopy: detection the coherent cyclotron radiation emitted by the beta-decay electrons in a magnetic field. The electron energy can be determined from the emitted radiation by finding the relativistic shift of the cyclotron frequency. We are constructing an ^83mKr source, which emits conversion electrons at 32.1 and 9.4 keV. The source will be useful in characterizing proposed experimental designs, and be an absolute energy calibration for the final design. )
