A betatron magnet having at least one electron injector positioned approximate an inside of a radius of a betatron orbit, the betatron magnet further includes a first guide magnet having a first pole face and a second guide magnet having a second pole face. Both the first and the second guide magnet have a centrally disposed aperture and the first pole face is separated from the second pole face by a guide magnet gap. A core is disposed within the centrally disposed apertures in an abutting relationship with both guide magnets. The core has at least one core gap. A drive coil is wound around both guide magnet pole faces. An orbit control coil has a core portion wound around the core gap and a field portion wound around the guide magnet pole faces. The core portion and the field portion are connected but in opposite polarity.
