A contract for multipole superconducting wiggler design and fabrication between The University of Saskatchewan and Budker Institute of Nuclear Physics was signed in October 2003. A wiggler with the photons energy range 4 to 40 keV, the maximum field 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 in BINP. To eliminate the undulator-type spectrum, the periodicity of the wiggler was broken. A new approach to the cryostat design enabled long-time (up to 6 months) machine operation without liquid helium refilling (LHe consumption <0.03 l/h). After successful tests the wiggler was installed on the Canadian Light Source (CLS) storage ring with the energy 2.9 GeV in January 2005. 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. 相似文献

A superconducting 119-pole wiggler with a 2.1-T operating field and 30-mm period length, which is intended for use at the ALBA Synchrotron Light Facility (SLF), Barcelona, Spain, has been designed and manufactured at the Budker Institute of Nuclear Physics, Siberian Branch, Russian Academy of Sciences, Novosibirsk, Russia. The interpole gap and aperture of the beam are 12.6 and 8.5 mm respectively. The total radiation power reaches 16 kW when the current of the 3-GeV electron beam is 0.4 A. In May 2010, after successful testing in Novosibirsk, the wiggler was transported to the ALBA SLF and was retested outside of the storage ring. The maximum field achieved by training of the magnet is 2.26 T. Owing to the improved cryostat structure, the equilibrium operating temperature of the magnet is brought down to 3.5 K, guaranteeing reliable operation of the device and zero liquid helium consumption. The basic parameters of the wiggler??s magnetic and cryogenic systems, as well as the results of their tests, are presented. 相似文献
