    摘要： First and second sets of thermionic cathode emitter filaments are wound into a composite cross-wound helical cathode emitter structure. The helical cathode emitting structure is supported at opposite ends by means of electrical terminals for passing electrical current through the cross-wound filaments. At one end of the composite mesh, the filaments have inwardly directed terminal portions terminating on the terminal support structure, whereby the inwardly directed terminal portions of the filaments permit a certain degree of flexibility to accommodate unequal thermal expansion of the support and mesh and whereby the cooling effect of the terminal structure is generally limited to the inwardly directed terminal portions of the filaments. The terminal structure also includes flexible support fingers to further accommodate unequal thermal expansion.
