Ta-al alloy attenuator for traveling wave tubes and method of making same |
| abstract |
The high frequency attenuator in a traveling wave tube and in other devices, in which the attenuator is disadvantageously subject to electron and/or ion bombardment, comprises an alloy coating of tantalum and aluminum. Also described is a process of fabricating such coatings in which the alloy is sputtered from a planar cathode comprising an aluminum plate and a perforated tantalum plate mounted on the aluminum plate. |
