Abstract
The tubular radiation absorbing device () for solar thermal applications has a central tube () and a glass tubular jacket () surrounding the central tube () so that a ring-shaped space () is formed between the central tube () and the tubular jacket (). The ring-shaped space () contains at least one inert gas with a partial pressure of 3 to 200 mbar. Alternatively in another embodiment a gas-tight closed container () filled with at least one inert gas is arranged in the ring-shaped space (). The container () has a device for supplying inert gas to the ring-shaped space () in order to compensate for increased heat losses due to diffusion of hydrogen into the ring-shaped space () from the heat carrier medium.
