多气隙电阻板室（MRPC）是一种高时间分辨的气体探测器，已经在高能物理实验中广泛应用于建造飞行时间系统进行粒子鉴别。随着高能加速器实验的能量和亮度不断提高，MRPC的计数率能力成为限制其发展的主要因素。影响MRPC计数率的主要原因，是随着工作电流的增加，高体电阻率的电阻板上产生的分压，降低了气隙中的实际工作电场。随着材料科学的发展，技术上已经能够方便的在材料表面施加均匀、可控的表面电阻层，并在微结构气体探测器领域率先得到应用，例如类金刚石碳基薄膜技术（DLC）。. 本项目开创性的提出，通过在电阻板的所有表面形成连续的阻性电阻层，利用表面电阻加速雪崩电荷中和，从而提高MRPC的计数率能力的新方法。项目将重点研究：适用于MRPC工作特点的DLC阻性层制作工艺和表面电阻率控制方法；通过模拟和实验相结合，探索表面电阻型MRPC的工作机理和设计方法，达到提高MRPC计数率性能的目标。

The Multi-gap Resistive Plate Chamber (MRPC) is a gaseous detector with very good time resolution. It has been widely used as the Time-of-Flight (TOF) system in many modern high energy physics experiments for Particle Identification (PID). With the increased beam energy and luminosity of the new generation accelerator experiments, the application of MRPC has been limited by its rate capability. The main reason is that the voltage drop on the high volume resistive plate decreases the working field in the gas gap when the current goes higher with the incident particle flux. With the developing of the modern material science, it is possible to generate uniform and controllable resistive layer on the designated surface. This technique has already been used in the Micro-Pattern Gaseous Detector (MPGD) community, e.g. the Diamond-like-Carbon (DLC) method..In this project, a new method is carried out for the first time to increase the rate capability of MRPC with a continuous resistive layer covers all surfaces of a plate. Under such a configuration, the avalanche charges will neutralize easily along the surface instead of through the volume. To achieve this, the R&D efforts will be focused on two main emphasizes. First, the methodology of the DLC resistive layer which satisfied the requirements of MRPC and the method to control the surface resistivity. Second, the work mechanics and the design of MRPC with surface resistance by the combination of both simulation and experimental approaches. Finally, the goal of increasing the rate capability of MRPC can be achieved.
