The PROSPECT experimental detector system as set up adjacent to ORNL's High Flux Isotope Reactor.
The PROSPECT experiment is the search for the transformation of electron antineutrinos produced in a reactor into a new form of matter - sterile neutrinos. It involves measuring the energy of antineutrinos coming from the High Flux Isotope Reactor (HFIR) at ORNL. This experiment will produce the most precise measurement of the 235U antineutrino energy spectrum in the world.
