We discuss a very high resolution imaging microchannel plate (MCP) detector developed for use in a high resolution ((lambda) /(Delta) (lambda) equals30,000) ultraviolet spectrograph which will fly aboard a NASA sounding rocket. The detector utilizes hybrid anode, referred to as a double delay line, which encodes x-axis position from time delay measurements and y-axis position by charge division. The detector uses low resistance MCP's in a z-stack arrangement to achieve high local count rates and a gain of 2 X 107 electrons per incident photon. The detector has a resolution of 20 micrometers FWHM throughout a 6x1 cm active area. The use of a KBr photocathode and a repeller grid boosts the quantum efficiency of the bare MCP's to over 40% at approximately equals 1100 angstroms.
