(under subclass 501) Subject matter wherein the space discharge tube means includes two large, flat, hollow, semicircular segments of thin metal placed with their diametric edges closely parallel, the two segments being given a high frequency alternating potential difference, producing a rapidly oscillating field in the space between them, whereby a free charged particle (e.g., proton, deuteron, or alpha particle) released in the space is caused to be pulled first in one direction and then another.
(1) Note. The influence of a magnetic field perpendicular to the plane of the segments causes the free particles to follow a circular path (i.e., as in a cyclotron).
