ABSTRACT:
An electron collector apparatus for a traveling-wave tube includes a ceramic housing having a cavity formed therein. The interior surfaces of the cavity are coated with at least one layer of an electrically conductive material that is adapted to be coupled to a bias source. An aperture is formed in the cavity through which an electron beam may enter the cavity. As the electron beam impinges upon the cavity walls, the cavity walls heat and conduct heat into the housing. The housing conducts the heat to its outermost surface where it can be dissipated. The outermost surface of the housing is covered with an electrically conductive material that acts both as a Faraday cage and a base onto which heat exchangers and other cooling devices can be affixed.
