Abstract
An electron beam tube (17) having a longitudinal axis comprises a first component, such as a ceramic wall (5) and a second component such as a drift tube assembly having a mounting plate (3). The tube further comprises means, such as member (18), 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.

An electron beam tube having a longitudinal axis and comprising a wall forming part of a vacuum envelope, a balance ring, a mounting component and a member interposed between the balance ring and the mounting component, the member having a lower coefficient of friction than both the balance ring and the mounting component, whereby the member is arranged to allow relative sliding movement between the balance ring and the mounting component in a radial direction.
An electron beam tube of the type having a longitudinal axis and a radial axis and a radial axis and a comprising a wall, a balance ring and a mounting component, the wall comprising part of a vacuum envelope and being coupled to the mounting component by the balance ring in the direction of the longitudinal axis, the electron beam tube further comprising a member interposed between the balance ring and the mounting component to allow relative sliding movement between the balance ring and the mounting component in a direction parallel to the radial axis, the member having a lower coefficient of friction than both the balance ring and the mounting component.
