Abstract
An electron beam tube () having a longitudinal axis comprises a first component, such as a ceramic wall () and a second component such as a drift tube assembly having a mounting plate (). The tube further comprises means, such as member (), arranged to allow relative sliding movement of the first component relative to the second component in a radial direction. The invention helps to alleviate mechanical stresses caused by differential thermal expansion of the components.
