Halbach, K

An improved wiggler having means for adjusting the magnetic field generated by electromagnet poles spaced along the path of a charged particle beam to compensate for energy losses in the charge particles is described which comprises; (a) windings on at least some of the electromagnet poles in the wiggler; (b) one of the windings on each of a group of adjacent electromagnet poles connected to a first power supply, and another winding on the electromagnet poles having more than one winding connected to a second power supply; and (c) means for independently adjusting one power supply to independently vary the current in one of the windings on a group of adjacent electromagnet poles; whereby the magnetic field strength of a group of adjacent electromagnet poles in the wiggler may be changed in smaller increments.
