Probing Neutrino Magnetic Moments at Underground Detectors with Artificial Neutrino Sources
Abstract
Neutrino-electron scattering can be used to probe neutrino electromagnetic properties at low-threshold underground detectors with good angular and recoil electron energy resolution. We propose to do this using a number of artificial neutrino and anti-neutrino sources such as 51Cr24 and 90Sr-Y. The neutrino flux is known to within one percent, in contrast to the reactor case and one can reach lower neutrino energies. For the 90Sr-Y source we estimate that the signal expected for a neutrino magnetic moment of μ=6 × 10-11μB will be comparable to that expected in the SM and corresponds to a 30% enhancement in the total number of expected events.
