Abstract

We describe a balloonborne telescope devoted to millimeter observations of diffuse sky radiation and optimized with a custom set of baffles and shields. The basic idea of the shield design is to shape the surfaces as roof mirrors to redirect the stray radiation in the opposite direction of incidence. The baffles are used to stop radiation close to the field of view. In this way we are able to avoid most of the unwanted radiation. We successfully operated this telescope (ARGO) during two flights, in 1989 and 1993, while detecting the faint structures of the cosmic microwave background at degree scale.
