Abstract

The AXAF CCD Imaging Spectrometer (ACTS) is currently being defined as a possible focal plane instrument to be flown on the Advanced X-ray Astrophysics Facility (AXAF). The imaging spectrometer consists of an array of charge coupled devices (CCD's) to be placed at the focus of the AXAF mirrors. The array will provide high angular resolution (~ 0.5 arc seconds), moderate spectral resolution (~ 150 eV) over the energy range 0.1 to 10 keV, temporal resolution down to ti 60 p sec, and single photon quantum detection efficiencies of up to 90%. X-ray sensitivity for a point source exceeds 10^-15 ergs/cm² sec fort a 10⁵ sec exposure. When used in conjunction with the objective gratings, the array will yield wavelength resolution of up to λ/Δλ of about 200.
