Abstract:
A method for producing various configurations of permanent magnet quadrupoles so that there is no coupling in the two transverse directions when focusing a charged particle beam is provided. Each configuration comprises a plurality of rotatable quadrupole disks, and means for rotating the quadrupole disks with respect to each other in a predetermined relationship.
