A Prototype Of X-Ray Imaging Device Based On The Gem Detector

A prototype of X-ray imaging device based on triple Gas Electron Multiply detector is studied. which has an effective gain up to 10(5) and can be used in high rate X-rays imaging. The precise method of micro-strip readout is designed for X-rays localization, and the crate controller of high-speed SCSI interface is applied for the data acquisition. The test results show that the position resolution of measurement system is less than 90mum and the stability of its effective gain is better than 1% under the X-ray flux of 10(5) Hz/mm(2).
