【 摘 要 】

The beam sweeping magnet kickers are two pairs of conductors placed 90 degrees apart inside a circular magnetic yoke. Each pair has the same excitation current in the opposite directions, and the two currents are a sine and a cosine in phase. To estimate the magnetic forces on the kickers due to the excitation currents, we make the following simplifications: (1) The four conductors are all parallel to one another; (2) There are no relative motions within the system; and (3) the magnetic yoke has {mu} = {infinity}, and the fields are zero near the outside inner surface of the yoke.
