Abstract
In a modified Betatron a low density background plasma is maintained in the vacuum chamber causing image charges in response thereto to form in the chamber wall. These image charges cause the self forces of the electron beam being accelerated in the betatron to be directed inward in the polodial plane thus eliminating injection problems, the diamagnetic to paramagnetic transition, and the l=2 resistive wall instability.
