Abstract: | SCUBA-2 will replace SCUBA (Submillimetre Common User Bolometer Array) on the James Clerk Maxwell Telescope in 2006 and will be the first CCD-style camera for submillimetre astronomy. The instrument will simultaneously image at 850 and 450 microns using two focal plane arrays of 5120 pixels each. SCUBA-2 will map the submillimetre sky 1000 times faster than SCUBA to the same signal-to-noise ratio. This paper introduces the detector technology and the challenges faced in reading out a detector array cooled to ~120 mK. |
