A Bragg x-ray spectrograph was developed for pulsed diagnostics. It covers the wavelength region 2--100 A and accommodates two convex crystals and a time-resolving x-ray intensifier. The x-ray detector is a gated intensified camera incorporating a custom-designed microchannel plate (MCP) built into a microwave circuit for fast pulsing of four or seven separate images. Various photocathodes (Au, Ni, CsI, and MgF/sub 2/) have been deposited directly onto the microchannel plate to form the strip lines. The MCP is mounted above a high-quality phosphor screen coated on top of a fiber-optic faceplate. Time resolution is obtained by sequentially gating the independent strip electrodes on the MCP for subnanosecond electrical gating. A one-dimensional time-resolved spectral image can be obtained.
