REDUCTION OF MULTIPACTING BY MEANS OF SPATIALLY VARYING MAGNETIZATION

摘要

The present invention discloses an apparatus comprising an enclosure (10) suitable for forming a vacuum therein and means for at least partially suppressing the multipacting effect when a RF or microwave electromagnetic field is generated in said vacuum. In the apparatus, the means for at least partially suppressing the multipacting effect comprises means (12) for passively generating a locally varying magnetic field (16) in the vicinity of at least a portion of the inner surface of said enclosure.
