Development of a thick gas electron multiplier for microdosimetry

Abstract

A new tissue-equivalent proportional counter based on a thick gas electron multiplier (THGEM) was developed and tested for microdosimetry. A systematic test was conducted at the McMaster Accelerator Laboratory to investigate the overall performance of the prototype detector. A mixed neutron–gamma-ray radiation field was generated using the 7Li(p,n) reaction. The detector was operated at low voltage initially to test the stability and then the …
