ABSTRACT:
A technique for ensuring the rapid correction of both amplitude and offset errors in the deflectional movement of an electron beam along an X-ray emissive target is disclosed. The movement is monitored at at least two positions during a sweep and differences, between the two movements and a desired movement, at these positions are combined in unequal proportions to produce a corrective servo signal.
