Abstract
A solid heat-dissipating member having an axial aperture to slidably receive a collector of a traveling-wave tube, includes at least one radial hole opening to the axial aperture. A contacting element having a spherical surface is accommodated in the radial hole so as to be held in pressure contact with the collector under the action of a biasing spring arranged in the radial hole. The collector can be held in good thermal-conducting relation with the heat-dissipating member without the danger of seizing and can be smoothly withdrawn therefrom when required.
