Phys. Rev. ST Accel. Beams 5, 062402 (2002) [6 pages]Identification and correction of antisymmetric field components in combined function magnets
M. Seidl * See Also: Erratum Received 23 October 2001; published 12 June 2002 This paper investigates the identification and correction of antisymmetric field components in combined function magnets. A measurement procedure is developed to identify small field components on the order of 10-3 in the plane of the reference path. Furthermore, a method is proposed to compensate them by surface correction coils on the poles of the magnet. As an example, the measurement and compensation of antisymmetric field components in a 90° bending magnet of the double sided microtron HDSM at the MAMI-C electron scattering facility is simulated with the help of the electromagnetic design code tosca. ©2002 The American Physical Society
