Abstract

The low energy grating readout for the AXAF-I mission will be implemented with microchannel plates in conjunction with a novel semi-solid substrate strip charge detector. One axis of the charge detector consists of a conventional wire grid. The other axis consists of charge pickup strips formed on a ceramic substrate. This configuration allows the construction of a three segment detector with the approximate curvature of the Rowland circle. A prototype detector has been built and tested. Spatial resolution is commensurate with conventional crossgrid detectors (< 25 micrometers FWHM).
