A Facility for Studying Gas Mixtures for a Three-Cascade Gas Electron Multiplier

An experimental facility has been developed by MEPhI to study the spectrometric characteristics of gas mixtures for cascade gas electron multipliers (GEMs), which are widely used in modern tracking, Cherenkov, and synchrotron-radiation detectors designed for high-energy physics experiments. The characteristics of the gas mixture for the GEMs used in the BM@N international experiment (Joint Institute for Nuclear Research, Dubna) have been investigated. The applicability of this facility for laboratory works accompanying the Nuclear Physics and Technology master’s courses is noted.
