KARMEN (KArlsruheRutherfordMediumEnergyNeutrino experiment), a detector associated with theISIS synchrotron at theRutherford Appleton Laboratory. Neutrinos for study are supplied via thedecay ofpions produced when aproton 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.
Limits were set on neutrino oscillation parameters. The KARMEN results disagreed with theLSND experiment and were followed up byMiniBooNE.[1]
