摘　　要：详细讨论了微间隙室的基本结构、特性及其主要研究内容;并在此基础上,探讨了微间隙室采用金刚石薄膜作为阳极电极微条和阴极电极微条之间的极间绝缘材料的可能性和有效性。为在第三代同步光源上实现具有良好时间和空间分辨的成像实验或衍射实验,提供了一种潜在的辐射成像探测器。Micro gap chamber（MGC） is a new type of Two-Dimensional position sensitive detector having excellent properties on the space and time resolution, counting rate, 2D compact structure and the flexi- ble of application. It will become a candidate of a new tracking detector for high energy physics experiment. The basic structure and properties of MGC as well as its main research subjects are presented in this paper. Furthermore, the feasibility and validity of utilizing diamond films as the MGC gap material were also discussed in detail So, a potential radiography imaging detector is provided in order to realize X image and X ray diffraction experiment having very good spatial and time resolution in the 3rd Generation of Synchrotron Radiation Facility.
