The operation of a superconducting wiggler at TERAS.

A superconducting wiggler has been successfully installed at the ETL 800 MeV electron storage ring facility (TERAS). The operation of the wiggler at magnetic field strengths of 5 T with electron beam energy of 750 MeV has been accomplished. The wiggler has been designed and constructed to produce synchrotron radiation with critical photon energy around 3 keV for scientific, industrial and medical applications. We report here experiments that demonstrate the possibility of stable operation of a superconducting wiggler in a small storage ring.
