Abstract :
Summary form only given. Microchannel plates (MCPs) are used in a variety of imaging systems as a means of amplifying the incident radiation. Using a microchannel plate mount recently developed at the University of Michigan, the effects of a metal reflecting grid are explored. Employing the reflecting grid, we create a potential difference above the MCP input surface that forces ejected electrons back into the pores, which may prove to increase the quantum efficiency of the camera. Using a characterized X-ray source, we investigate the changes in the pulse height distribution, modular transfer function, and quantum efficiency of MCPs caused by the introduction of the reflecting grid
