As part of their participation in the NA61/SHINE International Experiment at CERN, scientists from the Laboratory of High Energy Physics at JINR conducted complex study on methods of analysing waveforms produced by the Multigap Resistive Plate Chambers.

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 analysing complexity of the waveforms produced by the MRPC with DRS4 readout, a reliable algorithm needs to be developed in order to distinguish signal from noise.

VBLHEP JINR specialists investigated two methods, using the beam test data on MRPC with DRS4 readout held at the Pakhra Accelerator Complex at RAS Lebedev Physical Institute, Troitsk. The results are estimated within the comparative approach. The possibility of implementating these methods for different purposes is discussed.
