ABSTRACT:
A travelling wave tube arrangement is provided in which in order to support and cool the collector thereof the latter is cradled between two slabs of beryllium oxide attached to the walls of a channel in a block of copper, which walls are inclined in V-fashion. A further slab of beryllium oxide is provided above the collector. This last mentioned slab is attached to a flexible copper alloy wall which is dependent from a copper alloy plate which extends across the top of the channel. The plate is brazed to the block. A screw passing through the plate exerts pressure upon said flexible wall which in turn urges the beryllium oxide plate carried thereby towards the collector thus pressing the latter between the three beryllium oxide plates to form a electrically insulating support of good thermal conductivity. The invention is also applicable to travelling wave tubes having multiple collectors, each collector being cradled between common slabs of beryllium oxide and subjected to pressure via a common slab of the same above the collectors.
