TL;DR
This paper evaluates the performance of a gas electron multiplier made from polyimide film, demonstrating its high gas gain, rate stability, and discussing its potential integration with MSGC technology.
Contribution
It presents the fabrication and testing of a GEM with polyimide film, highlighting its stable operation and potential for combined use with MSGC.
Findings
Maximum gas gain of 5000 with Ar/CH4(91/9)
Stable gas gain up to high rates of 2×10^4 1/(mm^2 s)
Discussion of GEM operation with and without MSGC
Abstract
The gas electron multiplier produced with the polyimide film 100 um thick. The maximum gas gain obtained with gas mixture Ar/CH4(91/9) was 5000. No decrease of gas gain with rates up to 2\cdot10^4 1/(mm^2 s) was observed. The possibility of operation of GEM with and without MSGC is discussed
