New type of x-ray imaging intensifier

A New type of X-ray imaging intensifier was studied and developed. This intensifier combined with a little focal spot X-ray tube and a miniature high voltage power supply. Our product had performances of small volume, light weight, portable, high luminosity, Low X-ray radiation density and real-time imaging in daylight. The Lixiscope had also characteristics of simple structure, simple process, long lifetime, low cost and easy to application and promotion. The qualification of the imaging tube and the system: field range 50 mm, brightness 15 - 20 Cd/m2, screen resolution greater than or equal to 5 lp/mm, X-ray tube current 0.05-0.10 mA, target voltage 40 - 60 KV (continuous adjustable), DC/AC available, portable 2.5 Kg. To improve the X-ray imaging intensifier, we adopted several technologies as below. The little focal spot X-ray tube (0.5 mm2) and X-ray collimator was used to increase the resolution, maximum 10 lp/mm, the fiber faceplate or light cone output window to increase brightness and field range, nd the large area and high resolution MCP to increase field range. So, the developed X-ray imaging intensifier had found the widely application.
