Design, Fabrication and Test of the Steering Magnet for the KOMAC Beamline

The Korea Multi-purpose Accelerator Complex (KOMAC) is operating a 100-MeV proton linac. The beamline facility of the KOMAC has both a 20-MeV beam and a 100-MeV beam for users. Steering magnets are added to the beamlines to adjust the position of the beam on the target. The uniformity and the harmonics of the magnetic field are computed by using the Poisson code, and the integrated magnetic field is computed by using the CST EM Studio. The designed magnets were fabricated, and the field's uniformity and the integrated field were measured. The designed and fabricated steering magnets were characterized, and the results are presented in this paper. The results are expected to improve the beam performance, in particular, accurate delivery to the target.
