Abstract
A method for detecting a high pressure condition within a high voltage vacuum device includes detecting the position of a movable structure such as a bellows. The position at high pressures can be detected optically by the interruption of a light beam reflected by a hemispherically shaped reflector. The hemispherical reflector allows the source light fiber to oriented parallel to the detection light fiber, providing a more compact and efficient fiber routing.
