A contract for multipole superconducting wiggler design and fabrication between the University of Saskatchewan (Canada) and Budker Institute of Nuclear Physics (BINP) was signed in October 2003. The wiggler with the photons energy range from 4 to 40 keV, the maximumˇeld 1.9 T and the period length as small as possible was required for the micro-XAFS beamline. In 2004 the 2 T 63-pole superconducting wiggler with the average period length 34 mm was fabricated at BINP. To eliminate the undulator type spectrum the periodicity of the wiggler was broken. A new approach to the cryostat design enabled the long time (up to 6 months) machine operation without liquid helium reˇlling (LHe consumption < 0.03 l/h). In January 2005 after successful tests the wiggler was installed on the Canadian Light Source (CLS) storage ring with the energy 2.9 GeV. The main parameters of the magnet and the cryogenic systems as well as magnet measurements data, cryogenic system test data and experimental results during machine operation on the CLS storage ring are presented.
