摘要：Disclosed is an electron beam drilling system wherein an optical fiber link isused to prevent deviant drilling. The position of fixtures within a vacuum chamber ismonitored by alignable fiber segments. The junctions of the segments form coupleswhich transmit light from a source to detectors when the fixtures are properlypositioned. The alignable fiber segments are mounted on and under the fixtures in amanner which integrally provides protection of the junctions from metal spatter. Thelight source and detectors are mounted external to the chamber; seals are providedwhere the fiber segments pass through the chamber wall. The detectors signal a controlsystem to only allow beam output when the fixtures and parts thereon are properlypositioned.
