Abstract: This invention relates to a device that comprises at least one collection unit (11), equipped with a collection tube (21) placed on supports (23), which is formed by an inner absorber tube (31) shaped as a continuous tube and an outer envelope tube (33). The collection unit (11) also comprises reflectors (15) that direct the radiation toward the collection tube (21). Moreover, the device comprises means (41, 43) designed to maintain the collection tube (21) space between the absorber tube (31) and the envelope tube (33) at a pressure of between 5·10?1-5·10?2 mbar. The main advantages of the invention include the reduction in the breaking of glass due to the lower stresses to fatigue, an increase in the effective collection surface (97%-99%) and active management of the vacuum, which makes it possible to monitor the evolution thereof at all times.
