Scientific paper

Thermal protection applied to the IRAM 15-m mm-wavelength and 30-m mm-wavelength telescopes and their thermal behavior are discussed. The design of the passive/active thermal protection of these telescopes is based on dynamic time-dependent model calculations, which are explained and compared with in situ recorded temperatures of the telescope components. It is demonstrated that dynamic model calculations are capable of reproducing the observed thermal behavior of significant structural components with sufficient precision. It is pointed out that continued monitoring of the thermal behavior may lead to further improvements the performance of a telescope.
