Abstract: A permanent magnet structure comprising a linear array of hollow cylindrical flux source structures nested one within another about a common central axis. Each HCFS structure is free to displace linearly parallel to the central axis or to rotate about the axis. The array may be arranged by appropriate mechanical adjustment to provide periodic magnetic structures suitable for use as a wiggler or a twister.
