"Observing With ACIS"
by
Gordon Garmire 
An overview of the ACIS instrument on the AXAF satellite.
ACIS is the CCD imager, and combines an imaging spectrometer with high
angular resolution and moderate energy resolution and a grating readout
array which, in combination with the HETG grating instrument, provides
very high energy resolution from a slitless spectrometer.
