SCUBA-2: A 10000-pixel submillimetre camera for astronomy

We describe the current status of the SCUBA-2 sub-mm camera for astronomy. We describe the first measurements made while operating an entire sub-array, rather than small subsections as has previously been the case. These results demonstrate that the procedure required to set up the multiplexer for full sub-array operation can be carried out entirely automatically, and that the pixels are sufficiently uniform for the whole sub- array to be usefully operated simultaneously.
