Description
Summary:A bipolar correction magnet with permanent magnets for future accelerators such as ILC is proposed, which is realized by rotating permanent magnet rods. The shape of the magnet rods is adjusted, reducing sextupole and decapole components so that the flatness of the magnetic field distribution becomes better than 5e-5 [T] within ±10 mm range. The structure and the field adjustment scheme of a conceptual design is discussed.
