| Abstract | Abstract — We describe the current status of the SCUBA-2 sub-mm camera for astronomy. Current continuum (broadband) instruments for sub-millimetre astronomy (wavelengths of a few hundred μm to a few mm) are severely limited by the small number of pix-els. Instruments have moved from a single pixel to hundreds over the last decade, and further increases in pixel count are necessary to exploit existing and future telescopes. Another aim is to achieve background limited performance (BLIP), in which the noise limit is set by photon noise from back-ground radiation. Bolometric detection is used, since this is the most sensitive method. Until recently instruments have generally used germanium semiconducting thermome-ters. However, despite having reached the fundamental noise limits, these detectors are not background limited for the best |
