Abstract / Description of output
SCUBA-2 is an innovative 10000 pixel bolometer camera operating at
submillimetre wavelengths on the James Clerk Maxwell Telescope (JCMT).
The camera has the capability to carry out wide-field surveys to
unprecedented depths, addressing key questions relating to the origins
of galaxies, stars and planets. With two imaging arrays working
simultaneously in the atmospheric windows at 450 and 850 microns, the
vast increase in pixel count means that SCUBA-2 maps the sky 100-150
times faster than the previous SCUBA instrument. In this paper we
present an overview of the instrument, discuss the physical
characteristics of the superconducting detector arrays, outline the
observing modes and data acquisition, and present the early performance
figures on the telescope. We also showcase the capabilities of the
instrument via some early examples of the science SCUBA-2 has already
undertaken. In February 2012, SCUBA-2 began a series of unique legacy
surveys for the JCMT community. These surveys will take 2.5 years and
the results are already providing complementary data to the shorter
wavelength, shallower, larger-area surveys from Herschel. The SCUBA-2
surveys will also provide a wealth of information for further study with
new facilities such as ALMA, and future telescopes such as CCAT and
SPICA.
