## [4.03] CUBIC: an X-ray CCD Spectrometer for the Diffuse X-ray Background

The CUBIC (Cosmic X-ray Background Instrument using CCDs) will be launched later this year to begin a three-year mission to measure the spectrum of the Diffuse X-ray Background. The instrument incorporates two CCDs for moderate non-dispersive spectral resolution in the bandpass 0.2 - 10.0 keV. The field of view is $5 \times 5$ degrees below 1 keV and $10 \times 10$ degrees above 3 keV. Observations will consist of 50,000 - 100,000 second integrations. The instrument was built at Penn State and has been delivered to Argentina for integration into the Argentine/US SAC-B satellite. We describe the instrument design and performance specifications and present calibration data.
