Method of assembling a focusing solenoid and a metal flange, and focusing device thus obtained

摘要

The present invention relates to a method of assembling a focusing solenoid and a metal flange. A layer 4 of alumina or magnesium oxide is deposited by plasma blowpipe onto the surface of the flange 2 which it is wished to place in contact with the solenoid. The solenoid 1 is bonded to the surface of the flange 2 covered with the layer 4 of alumina or magnesium oxide. Application to the focusing of microwave tubes in particular. <IMAGE>
