SCUBA-2: a large-format submillimeter camera on the James Clerk Maxwell Telescope

SCUBA-2 is a second generation, wide-field submillimetre camera under development for the James Clerk Maxwell Telescope. With over 12,000 pixels, in two arrays, SCUBA-2 will map the submillimetre sky up to 1000 times faster than the current SCUBA instrument to the same signal-to-noise. Many areas of astronomy will benefit from such a highly sensitive survey instrument: from studies of galaxy formation and evolution in the early Universe to understanding star and planet formation in our own Galaxy. Due to be operational in 2006, SCUBA-2 will also act as a "pathfinder" for the new generation of submillimetre interferometers (such as ALMA) by performing large-area surveys to an unprecedented depth. The baseline design, projected telescope performance and scientific impact of SCUBA-2 are discussed in the paper.
