KARMEN (KArlsruhe Rutherford Medium Energy Neutrino 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
A proton is a stable subatomic particle, symbol , H+, or 1H+ with a positive electric charge of +1 ''e'' elementary charge. Its mass is slightly less than that of a neutron and 1,836 times the mass of an electron (the proton–electron mass ...
beam strikes a target. It operated from 1990 until March 2001, observing the appearance and disappearance of electron neutrinos. KARMEN searched for neutrino oscillations, with implications for the existence of sterile neutrinos.
Results
Limits were set on neutrino oscillation parameters. The KARMEN results disagreed with the
