UNDULATOR WITH DYNAMIC COMPENSATION OF MAGNETIC FORCES

摘要

A method and apparatus for implementing dynamic compensation of magnetic forces for undulators are provided. An undulator includes a respective set of magnet arrays, each attached to a strongback, and placed on horizontal slides and positioned parallel relative to each other with a predetermined gap. Magnetic forces are compensated by a set of compensation springs placed along the strongback. The compensation springs are conical springs having exponential-force characteristics that substantially match undulator magnetic forces independently of the predetermined gap. The conical springs are positioned along the length of the magnets.

1. An apparatus for implementing dynamic compensation of magnetic forces for undulators comprising:
an undulator including a respective set of magnet arrays, each set of magnet arrays attached to a respective strongback, and placed on horizontal slides and positioned parallel relative to each other with a predetermined gap; a respective set of compensation springs placed along each said strongback for compensating undulator magnetic forces; and said compensation springs include conical springs having exponential force characteristics, and said conical springs being positioned along the length of the magnets; and said conical compensation springs generating a mechanical force to substantially match said undulator magnetic forces independently of the predetermined gap.
