Abstract

1,057,009. Velocity modulated tubes. VARIAN ASSOCIATES. Dec. 4, 1964 [Dec. 23, 1963], No. 49512/64. Heading H1D. A travelling wave tube or a klystron has an integrated gun structure including a cathode and anode, wherein the structure is sealed to the main tube body by use of a de-mountable highvacuum joint. The cathode, focusing electrode and main accelerating anode forms the integrated gun structure, and this is sealed to a main body portion which forms part of the vacuum envelope and surrounds the interaction structure of the tube. A mechanical seal is made by providing two flanges, e.g. of stainless steel, one on the gun structure and the other on the main body portion, the flanges being bolted together with a sealing, gasket of copper located therebetween, triangular ridge portions on each flange ensuring an extremely high pressure in the region of contact between the gasket and the flanges. Alternatively, the grin structure may be brazed to the main body portion using a brazing composition having a liquidus temperature which is lower than the solidus temperature of any other brazed joint in the vicinity of the seal.
