Application of bent microchannel plates in recording systems of grazing-incidence spectrometers

摘要

The design of the grazing-incidence spectrometer, in the scheme of which microchannel plates (MCPs) elastically bent along the Rowland circle are used, is described. This scheme allows one to improve the matching of the spatial resolution of the MCP and the real spectral structure as compared with the outof- Rowland recording. The performed tests demonstrated the fivefold increase in the spectral resolution of the spectrometer.
