    Abstract: 本发明涉及磁控管,公开了一种磁控管及其阴极组件以及制造磁控管的阴极组件的方法,所述磁控管的阴极组件包括灯丝(10)和钼支架(22),所述灯丝(10)的两端分别与所述上钼帽(21)和下钼帽(22)通过焊料(30)焊接,所述焊料(30)以横向受阻的方式设置在所述上钼帽(21)和下钼帽(22)与所述灯丝(10)的焊接处。由于焊料以横向受阻的方式设置在上钼帽和下钼帽与灯丝的焊接处,因而在焊料熔化时,焊料的横向流动受阻,确保焊接的有效性和高质量,从而获得性能稳定的闭合回路。(20),所述钼支架(20)包括上钼帽(21)和下钼帽

    Abstract: A cathode for a secondary emission structure comprised of a superconductive material is described. In one embodiment the cathode comprises a layer of a superconductive material such as yttrium barium cupric oxide, or rare earth substituted neodymium cupric oxides. The layer may be bonded to a metal electrode or preferably the cathode consist of a superconductive or conductive oxide. The use of a superconductive material provides a cathode having suitable secondary emission characteristics and, furthermore, which being conductive at room temperatures, as well as, temperatures of operation of the cathode, obviating the need for a use of a very thin film of a secondary emission material.
