Abstract
The electron beam monitor includes two long, thin foil elements which are sequentially moved through an electron beam to be measured, in directions transverse to the beam and perpendicular to one another. The electron beam striking the elements produces forward directed bremsstrahlung radiation that is detected by a series of detectors which are positioned circumferentially about the beam path. A measuring circuit measures the radiation intensity as a function of the foil position to provide beam current, profile and position information. To simultaneously monitor a second beam travelling in a direction opposite to the first beam, a second series of detectors are positioned circumferentially about the beam path to detect forward directed radiation produced by the second electron beam as it strikes the foils.
