A short history of ’near-field' reactor antineutrino measurements at LLNL

Abstract: Since the early 2000s, our group at LLNL and collaborators have pursued many antineutrino measurements within 10s of meters of nuclear reactors. These studies have been motivated by both neutrino physics and the potential to monitor reactors in support of nonproliferation. In this talk I will review these efforts, tracing the evolution of project goals, physics opportunities,  and technology development. Highlights include the SONGS monitoring demonstrations conducted just down the I-5, results from the PROSPECT short baseline oscillation experiment, and recent development of highly capable organic scintillator instruments.
