Description
Permanent magnet Halbach arrays are used for beam steering and focusing for synchrotron light sources, Fixed Field Accelerators, and plasma accelerators. Conventional implementations require many custom wedge-shaped magnets with tailored geometries and magnetization angles, preventing material reuse. We present a method for constructing Halbach arrays from many identical rectangular magnets, each rotated in the transverse plane to approximate the ideal configuration. Although this introduces gaps and reduces magnetic efficiency compared with optimised wedge designs, it simplifies fabrication, lowers costs, and enables the magnets to be redeployed for future applications. A prototype array based on this approach has been built for Project TURBO at the University of Melbourne, and measurements confirm that the magnetic field quality meets the requirements of the planned beamline. Construction of the full arrays for TURBO is underway, and the reusability of the magnets is expected to provide long term flexibility for subsequent accelerator projects.
