<p>A klystron having a collector (2) and a drift tube (1) is provided with a vacuum retaining ceramic tube (8) between the drift tube and the collector. The outer surface of the cermaic tube is coated with metal M and spaced from the inside surface of the ceramic tube is a deformable metal cylinder (16). A transmission line TL is created and the cylinder (16) is so bent that the transmission line is a half wave length long at the mid-frequency of the operating bandwidth.</p> |
