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.
For use with a traveling wave tube provided with an electron gun assembly within a sleeve and at least one isolator therebetween, wherein the sleeve has a radius smaller than the radius of the at least one isolator, a method of mounting the parts of the assembly comprising:
