Abstract
Performance of the gas-filled detector prototypes based on the GEM, TGEM, and Micromegas technologies was studied with the aim of selecting variants for tracking detectors of the muon system for the CBM Experiment. The study was performed on the test beam of the proton accelerator at the Petersburg Nuclear Physics Institute (PNPI). Three-component mixtures based on Ar and He were used as the working gas. For all tested detector prototypes, the detection efficiencies were measured, and the modification of the amplitude spectra as a function of the incident beam intensity was investigated.
