Heavy Ion and Proton Irradiation of Gas Electron Multipliers With Liquid Crystal Polymer Insulator: Evaluation Tests for Use in Space

Abstract

Gas electron multipliers with a liquid crystal polymer insulator (LCP-GEMs) can be employed as X-ray polarimeters in several satellite missions in low-earth orbit. To evaluate their resistance to radiation, LCP-GEMs were exposed to Fe ion and proton beams from the heavy-ion accelerator facility HIMAC, and the gas gain was monitored. The LCP-GEMs survived 14… (More)
