Signal classification algorithms for the MRPC with DRS4 readout

Abstract

The readout electronics of the Multigap Resistive Plate Chambers (MRPC) of the NA61/SHINE experiment at CERN are based on the Domino Ring Sampler v.4 (DRS4) chips. Due to the analyzing complexity of the waveforms produced by the MRPC with DRS4 readout, one needs to develop a reliable algorithm in order to distinguish signal from noise. Two methods are investigated, using the beam test data on MRPC with DRS4 readout held at “PAKHRA” accelerator in LPI RAS, Troitsk. Their results are estimated within the comparative approach, as well as the possibility of their implementation for different purposes.
