Reines Delves Deeper In His Search for Neutrinos

Frederick Reines, now dean of the School of Physical Sciences at the Irvine campus, University of California, has moved his neutrino‐detection equipment to a deeper part of a South African salt mine. Three times as sensitive as it was before, it has moved down 47 meters to a depth of 3300 meters. Reines is running experiments at three different installations: the one in South Africa, another in a salt mine near Cleveland and a third near an AEC reactor in South Carolina. The effort is a collaboration among Irvine, Case Western Reserve (with M.F. Crouch and Robert Woods Jr) and the University of the Witwatersrand (with J.P.F. Sellschop).
