Abstract

PURPOSE:To make the size of a travelling wave tube power supply small and to realize a travelling tube amplifier whose heat dissipation is suppressed by interposing and arranging a metallic joint to a high voltage lead wire so as to vary its substantial length thereby avoiding a change in the arrangement even in the case of reuse of the lead wire. CONSTITUTION:A diode 4 is interposed to a part of a high voltage lead wire 3 on the way of the wire and a metallic joint 5 is interposed to a part on its way. The joint 5 is screwed to cut ends 3a, 3b of the lead wire 3 by a screw mechanism, for example and the interval of the cut ends 3a, 3b of both the lead wires is varied by turning the joint 5 around the shaft. Thus, even when the power supply 1 and a traveling wave tube 2 are disconnected and then connected for the reuse, the substantial length of the lead wire 3 is set to the same length as before by adjusting the joint 6. Even when the diode 4 is heated through the interposition of the diode 4 into the lead wire 3, the head in the power supply 1 is suppressed and the power supply 1 is made small in size.
