An explanation is offered for the ring structure and some of the other configurational details associated with negative ion spots on fluorescent screens. Negative ion liberation by positive ion bombardment and the effect of the magnetic deflecting field on the positive ion paths are believed responsible for the apparent selective focusing of negative ions.
