| Abstract: | A 10 cm×10 cm GEM detector was made by three-layer GEM foils.The 2D strip readout mode was used and each dimension has 256 channels with pitch of 400 μm.The APV25 front-end readout chip was introduced in the detector,and the backplane connectors were improved in order to adapt the electronics system with GEM detector.The detector achieved the experimental spatial resolution of 76 μm.In 2D X-ray imaging experiment,the clear image was obtained,which indicates the good working reliability of the GEM detector and electronics. |
