<p>Disclosed is a radiation collector comprising a pressure cell which is subdivided into a first pressure chamber and a second pressure chamber by means of the concentrator. The small pressure difference between the pressure chambers keeps the concentrator operational in a beam-concentrating form and reduces the wear on the reflective layer of the concentrator. The radiation collector further comprises adequately designed means for establishing the desired pressure in the respective pressure chamber, said means making it possible to compensate changes of the pressure chamber volume resulting from wind load, for example.</p> |
