| Summary: | © Published under licence by IOP Publishing Ltd. This study focuses on magnetic field simulation of a square-frame steering magnet and electron beam dynamic simulations in its magnet's field at the PBP-CMU Electron Linac Laboratory, Chiang Mai University. The small dipole magnets with the same design were constructed from four identical iron bars winding with 70 turns of copper-wire. They are used for steering electron beam with a maximum kinetic energy of about 2.0 MeV in the pre-injectors system of the electron accelerator. The magnetic field simulations were conducted by using computer programs POISSON and RADIA for two-dimensional and three-dimensional models, respectively. The maximum magnetic fields at an excitation current of 1 A were 44.30 and 57.32 Gauss for the 2D and 3D models, respectively. The magnetic effective length was 10.45 cm. The electron beam dynamic simulations in the 3D magnetic field map was performed by utilizing a computer program ASTRA to investigate the transverse electron beam distribution along the magnetic axis. The achievement of this study will be used as an important information for proper operation of the magnets at our facility. |
