Abstract

Detailed tests and analysis of ageing effects of high irradiation dose on Multi-Strip Multi-Gap Resistive Plate Counters based on low resistivity glass electrodes were performed. MSMGRPC efficiency and cluster size before irradiation are measured and compared with their values after irradiation in a high irradiation dose accessed at a multi-purpose irradiation facility of IFIN-HH based on $^{60}$Co source. The composition and properties of the deposited layers on the glass electrodes, studied based on a multitude of analysis methods, i.e. SEM, XPS, foil-ERDA, RBS, AFM and THz-TDS, are presented.
