For decades, catching neutrinos meant building bigger and bigger machines. In 2017 the COHERENT experiment turned that logic on its head with a 14.6-kilogram detector small enough to carry by hand. A look at how it works and why a small detector can sometimes do what a giant one cannot.
A new generation of compact, ultra-low-threshold detectors is being deployed near nuclear reactors to measure coherent elastic neutrino-nucleus scattering with high precision. The results will sharpen tests of the Standard Model and constrain a wide range of new-physics scenarios.
A compact antineutrino detector parked outside a nuclear reactor can, in principle, tell what fuel is being burned inside — including whether plutonium is being produced for weapons use. The technology is now being demonstrated in field-deployable form.
For years, dark matter direct-detection experiments improved sensitivity by orders of magnitude with each new generation. They are now bumping into an irreducible background — the steady drizzle of cosmic neutrinos passing through the planet.
In 1974, physicists predicted that low-energy neutrinos should occasionally scatter coherently off entire nuclei. In 2017, COHERENT finally caught the process. Now the field is moving fast.
