Sirius-Details of the New 3.2 T Permanent Magnet Superbend

An all permanent magnet superbend is proposed for the new Sirius optics and it can now provide hard X-rays in a critical energy of 19 keV. In the new design, the superbend has a stronger magnetic peak field of 3.18 T and it is composed of two low field parts designed with a transverse gradient on each side of the high field pole. The full magnet is joined into a single permanent magnet named BC and a floating pole links all three parts. The low field poles, the floating poles, and the return flux in the back can be adjusted to correct the integrated dipole and quadrupole components. The magnetic and mechanical design, assembly, magnetic measurements, and production strategy will be presented.
