BESSY operates a third generation synchrotron light source in VUV to XUV region at Berlin-Adlershof. The main radiation sources in storage ring are special magnetic elements such as undulators and wigglers. Three superconducting shifters and one multipole superconducting wiggler are operating giving enhanced photon flux for 10–25
keV X-ray region. As the superconducting elements presently are located in straight sections, BESSY intends to exchange four of the conventional room-temperature bending magnets by superconducting ones.
The report contains brief description of 9
T superbend prototype as a candidate for replacing of conventional magnets of BESSY-II, which was designed, fabricated and tested at Budker INP and was commissioned at BESSY in June 2004.
Main parameters of 9
T superconducting bending magnet prototype as well as testing results are presented.
