Abstract
In a traveling wave tube, an electron beam collector and an electrically insulating cylinder having good thermal conductivity and dielectric strength are arranged in a bore of a cooling housing to improve heat elimination from the electron beam collector. The cylinder is deformable in a radial direction, is of an elastic material, and is dimensioned so that it fixes the electron beam collector in the bore of the housing with a tight fit.
