Abstract
SCUBA-2 is an innovative 10,000 pixel submillimeter camera due to be
delivered to the James Clerk Maxwell Telescope in late 2006. The camera
is expected to revolutionize submillimeter astronomy in terms of the
ability to carry out wide-field surveys to unprecedented depths
addressing key questions relating to the origins of galaxies, stars and
planets. This paper presents an update on the project with particular
emphasis on the laboratory commissioning of the instrument. The assembly
and integration will be described as well as the measured thermal
performance of the instrument. A summary of the performance results will
be presented from the TES bolometer arrays, which come complete with
in-focal plane SQUID amplifiers and multiplexed readouts, and are cooled
to 100mK by a liquid cryogen-free dilution refrigerator. Considerable
emphasis has also been placed on the operating modes of the instrument
and the "common-user" aspect of the user interface and data reduction
pipeline. These areas will also be described in the paper.
