Abstract

A double GEM detector for X-ray astronomy is under construction. In addition to the GEM foils and the readout board, the gas volume of the detector will also enclose the front-end electronics and the cabling. As a sealed detector in years long operation, a special attention must be paid on the aging characteristics of the detector. We have studied the outgassing properties of various detector construction materials. Our ultimate goal is to identify most of the chemical compounds released in the gas and estimate their impact on the aging properties of the detector.
