ABSTRACT:
Neutrinos are detected by allowing them to scatter on nuclei contained in a detector and by detecting the recoil of the nuclei. Because the probability of a neutrino being scattered is very low the probability is very high that a neutrino will only cause recoil of a single nucleus. On the other hand background radiation is likely to cause the recoil of a large number of electrons and/or nuclei so that neutrino scattering can be detected by distinguishing between the recoil of a single nucleus and the simultaneous recoil of a plurality of electrons
uclei. In one form of the detector the nuclei are present as minute superconducting metal grains which are held in the superconducting state. At low temperatures the grains have a very low specific heat and the scattering of a neutrino will cause a single grain to heat up and change from the superconducting to the normal conducting state. This change will result in a perturbation of an applied magnetic field, as a result of the Meissner effect, and the perturbation of the magnetic field can be detected, for example as an e.m.f. induced in a detector loop. Several different superconducting arrangements are described. A semiconductor arrangement for detecting nuclear recoil is also described. The neutrino detector can be used, among other things, for monitoring reactor activity and for prospecting for subterranean deposits of radioactive elements, minerals found in association with these elements, and oil and gas.
