Abstract
The measurement results of the radiation resistance of materials of a thick-layer gas electron multiplier (TGEM), which is considered as a candidate for active elements of calorimeters operating under high radiation loadings, are presented. The radiation resistance of the active element of an organic-scintillator-based hadronic calorimeter and light collection by a reemitting fiber, is measured for comparison. The obtained data, i.e., invariability of the signal from the TGEM up to 5 Mrad with an almost triple reduction of the signal from the scintillator, can be considered as a qualitative indicator of possible use of the TGEM as a detector operating at high radiation loads.
