Abstract
An arrangement of conduction-cooled travelling wave tubes includes multiple travelling wave tubes mounted on a common base, wherein the travelling wave tubes are thermally connected to the base so that during operation of the travelling wave tubes the base forms a heat sink for the travelling wave tubes, and the base is designed to accommodate multiple travelling wave tubes in terms of their dimensions along their beam axes so as to increase the number of travelling wave tubes per surface area unit of the base.

An arrangement (AN) of conduction-cooled traveling-wave tubes (WR), comprising multiple traveling-wave tubes (WR) mounted on a common base plate (BP);
- wherein the traveling-wave tubes (WR) are thermally connected with the base plate (BP) in such a manner that the base plate (BP) forms a heat sink with regard to the traveling-wave tubes (WR) during operation of the traveling-wave tubes (WR);
- wherein the base plate (BP) is configured in such a manner that it holds multiple traveling-wave tubes (WR) along its beam axes (SA), with regard to its dimensions (LE, BG);
- wherein a distance (X2) between the beam axes (SA) of adjacent traveling-wave tubes (WR) is reduced, so as to increase a number of traveling-wave tubes (WR) per surface area unit of the base plate (BP), in such a manner that adjacent traveling-wave tubes (WR) are arranged within their reciprocal magnetic influence;
- and
- wherein the reciprocal magnetic influence is taken into consideration when adjusting magnetic focusing of the traveling-wave tubes (WR).
A method for production of an arrangement of multiple conduction-cooled traveling-wave tubes (WR) on a common base plate (BP), comprising the steps:
- making available multiple conduction-cooled traveling-wave tubes (WR);
- making available a base plate (BP), which is suitable for holding the multiple traveling-wave tubes (WR);
- placing the traveling-wave tubes (WR) on the base plate (BP), so that the traveling-wave tubes (WR) and the base plate (BP) are in thermal contact;
- and
- adjusting the electron beam focusing of each individual traveling-wave tube (WR) under the influence of the other tubes.
