ABSTRACT:
A trajectory correcting device for electron tubes comprises an auxiliary trajectory correcting means capable of creating a magnetic field that corrects the effects of azimuthal drift of the beam between a first disk and a second disk. This drift is due to the non-uniformity of the main field between the two disks. This means may include several coils, through which currents flow, placed in the vicinity of the disks or between them. The device can be applied to multibeam klystrons.
