The Millimeter-wave laboratory (MWL) designs, builds and tests receivers for use in radioastronomy with a focus on academic activities and technological research. We are a heterogeneous group of astronomers, engineers, technicians and students, with a joint experience that covers from decametric to sub-millimeter techniques. The Laboratory begins with the transfer of the equipment from the Maipú Radio Observatory on the year 2000 and the relocation/upgrade of the MINI (1.2m mm-wave radio telescope) from Cerro Tololo to Cerro Calan. Today, we are involved in several projects related to mm-wave receivers in collaboration with a number of groups abroad. Together with the Department of Electrical Engineering (DIE), which runs a photonics laboratory, we have formed the Astronomical Instrumentation Group.
