DEVICE FOR THERMALLY CONTROLLING AN ELECTRON TUBE HAVING A RADIATING COLLECTOR, COMPRISING A SCREEN, A FLUID LOOP AND A HIGH-TEMPERATURE RADIATOR

摘要

The thermal control device for radiative dissipation equipment comprises: first means, for capturing at least some of the radiation emitted by the dissipative equipment within at least one predetermined wavelength range of the infrared spectrum; second means, for emitting radiation in at least one wavelength range; means for transporting heat over a distance between the first and second means. Application in particular to thermal control for a travelling wave tube of the type with a radiating collector, said tube having a collector extending to the outside of the walls of a vehicle intended to operate in a high-vacuum environment, the collector being fastened to a finned cooler. The invention also relates to a method of operating the device.
