A simple technique for manufacturing electrodes of multichannel wire gas electron multipliers was developed. The maximum proportional multiplication factor of ionization electrons K max = 10 3 was obtained when the chamber containing a multichannel wire gas electron multiplier was filled with a mixture of Ar + 10%C 2 H 4 at a pressure of 1 atm (abs.) and the drift (ionization) gap of the chamber was irradiated with β particles ( 63 Ni). Under irradiation with α particles, K max = 10 3 at a pressure of 1 atm (abs.) and 3 × 10 3 at 0.4 atm (abs.). When the chamber was filled with a mixture of Ne + 10%C 2 H 4 at a pressure of 1 atm (abs.) and exposed to β particles, K max = 4 × 10 3 was obtained.
