Research Progress and Development of Resistive Glass for Resistive Plate Chambers

摘要

Resistive Plate Chambers are planar, gaseous detectors made with electrodes and resistive plates, which is divided into single-gap (RPC) and multi-gap (MRPC). Such detectors have a simple structure, good time resolution, high efficiency, small dead zone, flexible signal readout mode and a relatively low cost, etc. Therefore, it has extensive and important applications in high energy physics, nuclear physics and other fields. The resistive glass plate has good stability and is less affected by the environments, which ensures the uniformity of the electric field inside the detector and makes the detector have lower dark current and noise. In this paper, the influence mechanism of resistive glass on detector performance was introduced firstly. Then the application and research status at home and abroad were summarized. On this basis, the existing problems in the research of resistive glass were expounded. Finally, according to the application requirements of RPC under the condition of high particle fluxes, the future development trend was analyzed and proposed. The author believes that it is the future development trend and direction in the field of resistive glass to carry out research on high-performance resistive glass materials and develop pure electronic conduction glass materials with volume resistivity of 10 ~9?.cm ~10 9?.cm through composition design and control. At the same time, in order to meet the manufacturing requirements of large area array detectors, the strength chemical stability and the possibility of batch manufacturing of the glass should also be fully considered in the development process of resistive glass.
