✦ Synopsis

The delay-line readout method is suitable for the position sensitive detectors in the early stage of high energy physics experiment at low-rate environment. In this paper, we present a fast delay-line circuit (cut off frequency: 0.7 GHz) equipped with a triple-GEM (Gas Electron Multiplier) detector for X-ray imaging. Using 8 keV X-rays and readout strips with 0.15 mm width and 0.4 mm pitch, the experiment result shows that the position resolution of the detecting system is less than 100 mm at a counting rate of 10 5 Hz. A full simulation model has been developed for the design of delay-line electric circuit.
