NPA Zoom Seminar, Jeff Martoff, Temple University, "The HUNTER Sterile Neutrino Search Experiment"
The HUNTER experiment (Heavy Unseen Neutrinos from Total Energy-momentum Reconstruction) is a search for sterile neutrinos with masses in the 20-300 keV range. The experiment uses a combination of AMO, nuclear and particle physics techniques to do kinematically complete missing mass reconstruction of neutrinos from 131-Cs electron capture decays. A magneto-optically trap (MOT) of 131-Cs atoms provides a pure sample of ~10^8 radioactive atoms suspended in EUHV with no inert material present.
