DESCRIPTION:Speakers: Vitaliy Shkaruba (BINP)\nOne of the directions of BI
 NP activity is the creation of multipole superconducting wigglers with the
  magnetic field levels from 2 T to 7.5 T which are installed on many SR so
 urces. Special efforts were made by BINP to develop the cryogenic system w
 ith zero liquid helium consumption. The next significant step became the d
 esign and creation of superconducting full size prototype of dumping wiggl
 er for CLIC project where supposed the installation of 104 wigglers. For o
 peration of CLIC dumping wiggler it is required the magnetic field of  3 T
  and the period about 50 mm with a beam vertical aperture of 13 mm. Design
  features of the wiggler which was proposed and created by BINP is the app
 lication of  the indirect cooling method. In this case Nb-Ti magnet with t
 he length of 1.8 m and the weight of 700 kg is located in a vacuum and is 
 cooled by four Gifford-McMahon cryocoolers.  To maintain the temperature a
 bout 4.2 K on the magnet it is used the tubes with circulating liquid heli
 um as the heat conducting elements.  To increase the efficiency of pre-coo
 ling down of the magnet it is used nitrogen-based heat pipes of siphon typ
 e.   The features of the magnetic and cryogenic systems of CLIC dumping wi
 ggler full size prototype and test results are presented in this article.\
