Abstract

Abstract A plastic beam counter and associated photomultiplier base are constructed for use at intense muon beams (up to several 10 7 μ −/s). In order to enable a most sensitive recognition of beam background, the beam counter signal is recorded with a fast waveform digitizer. A peak finding routine is developed that makes use of a generalized second-difference signal calculated from the waveform. A rejection of prompt beam background events better than a factor of 100 is achieved.
