Description
The JSNS^2 experiment aims to search for the existence of neutrino
oscillations with Delta m^2 near 1 eV^2 at the J-PARC Materials and
Life Science Experimental Facility (MLF). The combination of the 1 MW
proton beam (3 GeV), created by the Rapid Cycling Synchrotron (RCS),
and the spallation neutron target, provides an intense neutrino source
from muon decay at rest (mu+ --> e+ + numubar + nue). The oscillation
to be searched for is numubar to nuebar which is detected by the
inverse beta decay interaction, nuebar + p --> e+ + n, followed by
gammas from the neutron capture of Gd. The two detectors with a total
fiducial volume of 50 tons will be located 24 meters away from the
mercury target.
Additional physics programs include cross section measurements with
neutrinos from muon decay at rest (10s of MeV) and with monochromatic
236 MeV muon neutrinos from kaon decay at rest.
