Paper Abstract

Microchannel plate (MCP) stacks have proven very useful for imaging detectors in X-ray and UV astronomy 1,2. However, the back to back stack configuration of flat MCP's which we often use is not optimal for some applications. Firstly, there are variations in the performance (gain and pulse height distribution) of these stacks due to warpage of the individual MCP's. Secondly, for grazing incidence optics with a curved focal plane, a curved detector is often desirable. We have studied two MCP developments, bonded MCP stacks, and stacks of MCP's with curved surfaces to determine if we can achieve the MCP requirements for future astrophysical detectors. Our experiments show that both configurations studied give superior MCP performance characteristics. However, there seem to be some problems with the fabrication of bonded MCP stacks resulting in poor flat field characteristics and increased background.
