Filed: 1975-06-25
Abstract: 1510377 Discharge tubes THOMSON-CSF 25 June 1975 [28 June 1974] 27024/75 Heading H1D Parasitic waves generated at the end of a pair of coaxial cylindrical electrodes in a high frequency discharge tube are attenuated by a metal ring attached to the outermost electrode near its end, the ring including a plurality of energy absorbing elements in the form of elongated bands disposed around, and radially with respect to the ring. In the arrangement of Fig. 4, which is shown mounted between the coaxial electrodes 1 and 2 in Fig. 6, the metal ring 8 includes strips 12 of resistive material, e.g. of semiconductor, or of porous alumina filled with conductive or semiconductive material, the ring being supported by insulating pillars 10, which maybe of alumina or beryllia, from a metal disc 11 brazed to the end 4 of electrode 2. The strips 12 may interrupt the ring 8, or merely be surface deposits; alternatively they may be of high resistivity magnetic loss material, e.g. ferrite (Figs. 7 and 8, not shown). To avoid electrical isolation of the ring 8, it may be connected to the disc 11 via surge coils 13 wound round the pillars 10, or the pillars themselves may be of resistive material. To prevent damage to ring 8 due to thermal expansion, the strips 12 may at at least one side be connected to the ring by a metal spring. Reference is made to the use of the arrangement in the end cavity of a magnetron; adjacent the tuning piston of a tunable coaxial magnetron; and in the terminal cavity of a coaxial electrode tetrode (Figs. 12 and 13, not shown).
