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.
Claims18
An electron beam tube having a longitudinal axis and comprising a wall forming part of a vacuum envelope including a balance ring, a second component and means interposed between the wall including the balance ring and the second component arranged to allow relative sliding movement of the wall including the balance ring relative to the second component in a radial direction.
A tube as claimed in claim 10, in which the part is a mounting plate for the drift tube.
An electron beam tube having a longitudinal axis and comprising a drift tube assembly, a wall forming part of a vacuum envelope including a balance ring and means interposed between the wall including the balance ring and the drift tube assembly arranged to allow relative sliding movement of the drift tube assembly relative to the wall including the balance ring in a radial direction.
An electron beam tube of the type having a longitudinal axis and a radial axis and comprising a wall, a balance ring and a mounting component, the wall forming 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 of the balance ring and the mounting component in a direction parallel to the radial axis.
