Development of gas electron multipliers with Resistive Kapton electrodes

摘要

We successfully produced Resistive-Electrode GEM (RE-GEM) that was applied Resistive-Kapton to electrodes. We measured the gain curve of RE-GEM using an ⁵⁵Fe radioactive source in the gas mixture of Ar 70 % and CO2 30 %. We obtained the maximum gain of about 300 at an applied voltage of 740 V.
