Project 8 Collaboration
We are performing laboratory measurements and simulations to prepare for the 1-cubic-meter Atomic Tritium Demonstrator in Phase III of Project 8. This will confirm that we can produce, cool, and trap sufficient atomic tritium for the final Phase IV experiment.
Current work includes measuring the output of a tritium-compatible atom source with 20 sccm of H2, 20 times higher than published values; improvements in atom-detection SNR; corrections for systematic effects; calculations of the required atom flux into the trap; and simulations-driven optimization of the cooling stages downstream of the atom source.
*This work is supported by the US DOE Office of Nuclear Physics, the US NSF, the PRISMA+ Cluster of Excellence at the University of Mainz, and internal investments at all institutions.
