is the KA
eutrino Experiment, a detector associated with the ISIS synchrotron at the Rutherford Appleton Laboratory
. Neutrinos for study are supplied via the decay of pions
produced when a proton
beam strikes a target.
KARMEN's most noteworthy result to date has been an anomaly in detected event timings that may be interpreted as a heavy neutrino variant, possibly a supersymmetric neutralino particle.
