Development of a New X-Ray Image Intensifier for X-Ray Diffraction Studies

摘要

The development of a new X-ray image intensifier which utilizes a demountable caesium iodide low density cathode and a large area (120 mm diameter) channel plate multiplier to generate high photon gains with high spatial resolution is described. The spatial resolution is demonstrated at approximately 10 line pairs/mm with a quantum efficiency of 11.5% for 6 keV X-rays and a quantum gain of 8 x 10(6). Improvements in the cathode mountings are expected to increase these figures to the design values of 10(8) for the gain and 50% for the quantum efficiency.
