1. A method to operate a receiver with a heating area for heating a heat-transporting medium, and a transport arrangement for the transport of the medium through the heating area, the method comprising:
providing in the heating area, an opening for the radiation of the sun and an absorber is provided in the path of the incidental radiation of the sun, thereby absorbing the incidental radiation;
providing a gas absorbing within frequency bands belonging to the infrared range as a heat-transporting medium and operating parameters, a geometry of the heating area and a mass flow of the gas through the heating area of the receiver are set such that the gas is selected and the geometry of the heating area and the mass flow are balanced such that a temperature of the gas during transport through the heating area increases due to absorption of radiation such that a ratio of a temperature increase due to the absorption of radiation to an entire temperature increase due to the absorption and convection at the absorber is ≥0.5, wherein the gas is a heteropolar gas.
