Abstract

A radiometer based on SIS mixers for astrophysical observations is being assembled. The system, cooled to cryogenic temperature by a pulse tube refrigerator, is intended for operation on the Antartic Plateau during the local winter, using the mm dishes available there in the future. The system prototype will be tested at the focus of the 2.6 m MITO telescope at the Testa Grigia Observatory on the italian Alps. We discuss the system characteristics and the observational programs.
