Title: Push-pull betatron pair

Abstract

A push-pull betatron accelerator with two coaxial betatron tubes in which two electron beams are alternately accelerated in opposite directions of rotation. Both tubes are linked by the same alternating current accelerating flux produced by one or more accelerating flux coils. The betatron tubes are provided with guide fields having alternating current components which are in the same direction and having direct current biasing components which are in opposite directions. One electron beam is accelerated when the accelerating flux is changing between its negative maximum and its positive maximum, while the other beam is accelerated when the accelerating flux is changing between its positive maximum and its negative maximum. In another embodiment, there is only one betatron tube, in which two electron beams are alternately accelerated in opposite directions of rotation; and in still another embodiment, there are two tubes in which electrons are accelerated alternately, but the AC components for the guide fields are in opposite directions for the two tubes, while the DC biasing components are polarized the same for both tubes.
