【Abstract】 A new kind of gas detector based on gas electron multiplier (GEM) is studied for X-ray imaging of high luminosity. A single-GEM device is designed to test the property of GEM foil .The effective gain and counting capa- bility of a double-GEM detector are measured by an X-ray tube with Cu target. An initial X–ray imaging experiment is carried out using a triple-GEM detector and the position resolution of less than 0.1mm is achieved. The 3D distri- bution of electrostatic field of GEM mesh is also presented.更多还原
