Abstract:
An electron tube for use as a traveling-wave tube or the like comprises an longated housing having a central evacuated passageway therethrough and a plurality of annular magnets and circuit means supported within said housing at predetermined spaced locations along the length of said passageway within said housing. Preferably, the housing comprises a pair of generally semi-cylindrical mating ceramic substrate halves, each half including semi-annular grooves along the interior thereof which mate with respective semi-annular grooves of the other half to define annular grooves in which said magnets may be positioned or formed and annular portions of said circuit means may be deposited. Preferably, the respective ceramic substrate halves also have guide paths established therein for the reception of conductive material deposited therein to form the interconnecting portions of said circuit means.
