LABOCA is a multi-channel bolometer array for continuum observations. It was built by the bolometer (incoherent receivers) development group of the Max-Planck-Institut für Radioastronomie in Bonn.

The instrument was first installed at APEX in September 2006. It was then continuously improved until the commissioning and science verification in May/June 2007. Since then it has been available for regular observations. The LABOCA observing is usually organised in dedicated time-blocks because the operation depends on the availability of liquid helium on site. These time-blocks will usually be announced in the corresponding calls for proposals.

If you plan to use LABOCA for your research for the first time it is highly recommended to have a look at this lecture by Axel Weiss on the instrument, that covers all different aspects from the instrument characteristics, to data reduction or calibration.
