Abstract
A radio telescope consists of a pedestal, or an alidade or fork, of a BUS connected to the elevation structure or connected to the secondary focus cabin, of panels on the BUS that form the reflector surface, and of a quadripod with the primary focus cabin and subreflector (Fig. 1.1). Not all of these components are in direct thermal contact, but they are all exposed to the variable thermal environment or an artificial environment in a radome or astrodome. As the components are mechanically connected, a thermal inhomogeneity in one or several of the telescope components may introduce a mechanical deformation that may affect the performance of the whole telescope.
