Development of gaseous particle detectors based on semiconductive plate electrodes

Abstract

A new particle detector with sub-nanosecond time resolution capable of working in high-rate environment (rate capability of the order of $MHz/c{m}^2$) is under developmnet. Semiconductive electrodes with resistivity $\ddot{I}$ up to $10^8\hat{I}\text{c◯}\cdot cm$ have been used to improve the RPC [1] [2] rate capability. In this paper efficiency and time resolution of three different detector structures are presented.
