CUBIC Instrument Summary
Mission: SAC-B.
The CUBIC detectors are two CCDs viewing the sky through
a coarse pinhole camera. The instrumental properties are:
- Energy range: 0.2 - 10 keV
- Energy resolution: 2% at 6 keV
- Time resolution: 30 seconds
- Spatial resolution (E < 1 keV): 5 x 5 degrees FWHM
- Spatial resolution (E > 3 keV): 10 x 10 degrees FWHM
- Field of view (E < 1 keV): 15.9 x 10.8 degrees
- Field of view (E > 3 keV): 21.4 x 16.4 degrees
- Detectors: 2 EEV CCD-12-30-4-202 Charge Coupled Devices
- Collecting area: 4.7 square cm
- Etendue: 0.15 cm**2 sr at 4 keV (peak)
- Point source sensitivity: 30 mCrab (estimated)
Instrument Resources:
- Mass: 31.1 kg
- Power: 30 W
- Volume: 61.5 cm x 45.7 cm x 25.4 cm
- Telemetry: < 300 bits per second
More details on the CUBIC design are available in our
SPIE paper (22 pages)
and our
CUBIC Instrument Handbook.
Pictures of the SAC-B satellite
and CUBIC instrument are also available.
CUBIC was built by the High Energy Astrophysics Lab in the Department
of Astronomy and Astrophysics of the Penn State University
under the leadership of
Dr. David Burrows,
in collaboration with the
X-ray Astronomy Group of Leicester University.
