Abstract: An anode control circuit for at least two traveling wave tubes powered by a common electronic power conditioner. The anode control circuit has separate anode drive circuits for the traveling wave tubes that are referenced to a voltage that is higher than the cathode voltage being supplied by the electronic power conditioner. A relay between the anode drive circuit and the anode of the traveling wave tube being driven opens or closes a path between the traveling wave tube and the cathode voltage supplied by the electronic power conditioner. The anode drive circuits are referenced to one of the collector voltages that is closest to the anode operating voltage and such that the anode voltage is more positive than the reference voltage.

Abstract: A traveling wave tube having an electron gun and a collector assembly is provided. The assemblies include a sleeve placed around an isolator. The sleeve is either heat shrunk or heat deformed around the isolator. Heat shrinking is performed when the sleeve radius is initially larger than the isolator radius. During heat shrinking, the sleeve is heated to cause the sleeve radius to increase and be larger than the isolator radius. The sleeve is then placed around the isolator and cooled causing the sleeve to contract upon the isolator. Heat deformation is performed when the sleeve radius is initially smaller than the isolator radius. During heat deformation, the isolator is inserted into the sleeve. The isolator and the sleeve are then heated so that the sleeve expands to a constrained amount of expansion and then deforms. The sleeve and the isolator are then cooled causing the sleeve to contract upon the isolator.
