Soft x-ray cathode and its application in Lixiscope

In this text the photoelectric emission principle of X-ray cathode was introduced at first. Then we provided the manufacture method of CsI/MCP X-ray cathode, analyzed the quantum efficiency and noise characteristic of reflection type and transmission type X-ray cathode, proposed the improved process, provided the output characteristic and front and sectional stereoscan photograph of CsI/MCP and pointed out the development of Lixiscope and application prospect in biomedicine.
