Summary

The design of a 10-T superconducting wiggler as a synchrotron radiation source for angiography has been carried out to be installed in an 800-megaelectronvolt electron storage ring, TERAS, at Electrotechnical Laboratory, Ibaraki, Japan. Synchrotron radiation generated by the wiggler has a critical photon energy of 4.47 kiloelectronvolts and the radiation spectrum identical to that from a 2.5-gigaelectronvolt storage ring with a bending radius of 8.3 m. The magnet of the wiggler consists of three pairs of iron-cored superconducting coils designed to provide a peak field of 10.5 T on the beam trajectory. The effect of the wiggler on the storage ring has been investigated and a pair of quadrupole doublets on both sides of the wiggler can compensate a large deviation of the betatron tune.
