Abstract : Analytical and computer simulation results are reported on the dynamics of a high current electron ring in a conventional betatron accelerator. These studies include, in addition to the external and self fields, the effects of surrounding walls and toroidal corrections. Results show that, in contrast with the modified betatron, the equilibrium in a conventional betatron is incompatible with either large thermal energy spread or emittance. However, as in the modified betatron, the energy mismatch and the diffusion of the self magnetic field impose stringent constraints on the accelerator. Finally, in both devices, it is necessary to keep the ratio of the ring to the torus minor radii much less than unity. (Author)
