ABSTRACT:
A method for the manufacture of a helix-coupled vane line consists in cutting out, in a part comprising at least one channel, successive slots through the channel that extend beyond the channel so as to obtain portions of turns each fixedly joined to a vane; cutting out, in another part, a succession of fingers that are all fixedly joined to each other; connecting the turn portions to the fingers so that one end of a turn portion is connected to one end of a first finger and the other end of the turn portion is connected to the base of a second finger adjacent to the first finger; and separating the fingers from one another at their bases. Application of helix-coupled vane lines. Is most notably for crossed-field amplifiers.
