Title:	Generation of High-Energy Synchrotron Radiation with a 10-T Superconducting Wiggler
Abstract:	In August, 2002 a 10T superconducting wiggler was tentatively installed in the 8GeV electron storage ring at SPring-8 in order to check its performance and to investigate the effect on a stored beam. A beam was successfully stored in the storage ring at magnetic fields of the wiggler up to 9.7 T. The beam current was limited to 1mA to avoid unnecessarily high heat-load on photon absorbers and radiation damage to accelerator components. Beam parameters such as a horizontal beam size, a bunch length, betatron tune shifts were measured. A spectrum of high-energy synchrotron radiation in MeV-region was also measured with the NaI scintillator at an extremely low beam current of about 8pA. Results on these will be presented in the seminar.
