| Abstract: | A novel Micro-pattern gaseous detector(MPGD),thick GEM with electrodes made of a resistive material(RETGEM) is presented.In this paper we mainly investigate the energy resolution of a RETGEM in Ar+CO2 with different gas mixtures.The results indicate that an energy resolution 30% in single and double mode can be obtained.The existence of an optimum energy resolution is discussed. |
| Keywords: | RETGEM detector energy resolution Ar+CO2 single mode double mode |
