Description
Project 8, a neutrino mass experiment, employs the novel frequency technique of cyclotron radiation emission spectroscopy (CRES) to perform a model independent measurement of neutrino mass via tritium beta decay. Our pioneering experiment will consist of an atomic tritium beamline that dissociates molecular tritium, surface cools atoms with an accommodator, evaporatively cools and slows atoms, and traps them in a CRES resonant cavity to advance towards our sensitivity goal of 40 meV/c^2 for our final neutrino mass measurement.
At Indiana University, we are prototyping an electron cyclotron resonance (ECR) dissociator that uses a tunable 1 kW 2.45 GHz RF generator and a static magnetic field to ignite a hydrogen plasma in an aluminum resonant cavity operating in the TE111 mode. Our ECR source is designed to produce a high atomic flux (~10^19 atoms/second) at room temperature. This talk will present the engineering development, gas diagnostics, and spectroscopy data from our hydrogen plasma.
