Deflection of charged particles in the hundred GeV regime using channeling in bent single crystals

Abstract An experiment has been carried out to observe the deflection of charged particles by planer channeling in bent single crystals with momenta between 12 and 180 GeV and with angular deflections up to 27 milliradians. Anomalous losses of particles from the center point of a three point bending apparatus have been observed at high incident particle energy. This effect has been employed as a “dechanneling spectrometer” to study dechanneling effects caused by bending. The bending losses generally conform to theories of bending dechanneling based on the classical channeling model.
