|SUPAG10||Design Study of a Fast Kicker Magnet Applied to the Beamline of a Proton Therapy Facility||110|
Funding: Huazhong University Of Science And Technology
A proton therapy facility based on an isochronous superconducting cyclotron is under development in HUST (Huazhong University of Science and Technol-ogy). A fast kicker magnet will be installed in the up-stream of the degrader to perform the beam switch function by kicking the proton beam to the down-stream beam stop. The rising and falling time of the kicker is about 100us, and the maximum repetition rate is 500Hz. This paper introduces simulation and opti-mization of the eddy current and dynamic magnetic field of the fast kicker, by using FEM code OPERA-3D. For kicker materials, laminated steel and soft ferrite are compared and the MnZn ferrite is chosen. Design-ing considerations includes the eddy current effect, field hysteresis, and mechanical structure of the kicker will also be introduced.
