The HUNTER experiment is a search for sterile neutrinos with masses in the 10-300 keV range. The neutrino missing mass will be reconstructed from 131-Cs electron capture decays occurring in a magneto-optically trapped, laser-cooled sample. Reaction-microscope spectrometers will be used to measure the vector momenta of all charged decay products with high solid angle acceptance, and LYSO scintillators read out by silicon photomultiplier arrays detect x-rays, each with sufficient resolution to reconstruct the neutrino missing mass as a peak separated from the near-zero-mass active neutrinos. The stand-alone apparatus to do this has dimensions of a few meters.
