Popis: The multipole superconducting wiggler was designed, fabricated and successfully installed and tested on DELTA Synchrotron Radiation Source. The wiggler represents a multipole magnet with alternating high magnetic field of 7 Tesla along movement of particles in storage ring. The magnet is immersed into liquid helium of a special cryostat with working temperature of ~4.2K. The wiggler consists of 22 pairs of poles superconducting magnet with 18 full field poles, 2 with a three-quarter field strength and 2 with one-quarter field poles. The magnet array produces a sin-like magnetic field variation on the magnetic axis of the device with first and second field integrals close to zero. The Dortmund Electron Accelerator (DELTA, Germany) operated at 1.5 GeV synchrotron radiation source requires a superconducting wiggler as an insertion device for three x-ray beamlines with photon energies up to more than 30 keV. The wiggler has a period of 127 mm, magnetic field of 7 Tesla and the length from flange to flange of 2.2 m operated with zero boil-off mode. The conception and main approaches for the design of the magnetic and cryogenic system as well as the main parameters and the test results of new 7 Tesla superconducting wiggler for DELTA synchrotron light source are presented.
