In the past, efforts have been made to extend the current-carrying capability of the betatron by the addition of a toroidal magnetic field. The resulting ''modified betatron'' configuration provides high-current capability, but is limited to the same energy mismatch bandwidth as a conventional betatron. Field errors due to the toroidal field and the beam self fields require the modified betatron to have a larger energy mismatch bandwidth than a conventional betatron. By adding both a toroidal magnetic field and a strong focusing field to a betatron, one can achieve high current capability together will the required energy mismatch tolerance. The resulting configuration is a combination of stellarator and betatron (stellatron) fields. In this paper the authors consider the behavior of an l=2 stellatron which provides quadrupole focusing and is analagous to an alternate-gradient strong focusing system in a toroidal field.
