Abstract
A method for introducing a protective gas into an annular space of a receiver tube, in particular for solar collectors, is provided where the annular space is formed at least by one outer cladding tube and an inner absorber tube of the receiver tube and the outer cladding tube is connected to the absorber tube by a wall. The method includes producing an opening that penetrates the cladding tube or the wall, introducing protective gas through the opening into the annular space, and subsequently closing the opening.
