ORLaND: A proposed facility to investigate neutrino properties relevant toastrophysics

ORLaND, the Oak Ridge Laboratory for Neutrino Detectors, is a proposed unde rground facility adjacent to the target station of the Spallation Neutron S ource (SNS). The 1.3 GeV, 2 MV beam of protons striking the Hg target in 60 Hz, 600ns pulses mill be the world's most powerful source of intermediate e nergy nu (mu), nu (e), and <(<nu>)over bar>(mu). The possible experiments r elevant to astrophysics are discussed. This laboratory is planned as a gene ral user facility with space enough for a 2000 ton Cerenkov detector and 5 or 6 smaller detectors of between 50 and 200 tons. A proposed program is di scussed that includes the following cross sections measurements as examples : D-2(nu (e), e(-))pp, O-16(nu (e), e(-))F-16, Fe-56(nu (e), e(-)) Co, and many other reactions. A program of research and development of neutral curr ent experiments is also planned.
