New type of permanent magnet beam line optics

Name: Work Video:
Duration: 3 min 30 s
Description: A class of hybrid permanent magnet multipoles that use magnet retraction between ferromagnetic poles to achieve linear, independent field strength adjustments of 40% and micron level magnetic centerline adjustment are described. Scaling relationships, material choices, passive temperature stabilization, and design examples are discussed.
