Abstract
A digital system for an automatic beam alignment is described, capable of achieving a beam alignment of 10(-9) rd/square-rootHz for frequenc ies above 1 Hz. The usefulness of the digital system is based on its a bility to diagonalize the feedback matrix for any complex servo-contro lled subsystems included in large experiments.
