Development of combined-function multipole permanent magnet for high-intensity beam transportation

Fuwa, Yasuhiro ; Takayanagi, Tomohiro ; Iwashita, Yoshihisa*

Space charge compensation technique using multipole magnetic field components has been proposed to transport high intensity beam in the J-PARC linac. In order to realize this compensation technique, a compact size permanent hybrid multi-pole magnet would be suitable. A magnet system for the simultaneous production of quadrupole and adjustable octupole components using permanent magnet materials and have manufactured a first model of the magnet systems.
