Design of Superconducting Wiggler for a Synchrotron Radiation Facility
In a synchrotron radiation facility with an intermediate eletron beam energy of about 1.5GeV. hard X-ray is provided with the aid of a superconducting wiggler which generates a magnetic field of more than 4T. The superconducting wiggler is installed into an electron storage ring, and its influence to life time of the electron beam is the most important problem. In this paper, designing method of 3-pole superconducting horizontal wiggler is discussed by taking account of bending angle, maximum excursion of the electron beam, sextupole component of wiggler field and superconducting characteristics. The typical design of wiggler coils and the whole wiggler system including refrigerator are also reported.
