In 1999, in the frame of the project ISTC #767 “Budker INP/RIKEN Slow Positron Source”, the Budker Institute of Nuclear Physics had made a 10T Three-pole Superconducting Wiggler. The wiggler will be the keystone of this project by its installation on the SPring-8 storage ring for powerful gamma ray generation (λc=450keV), that will be used for slow positron production (N γ (ε>1MeV)∼10 15 , γ/s Ie=0.1A). A. Ando et al., Proposal of the high magnetic field super conducting WLS for slow positron source at SPring-8, presented at SR1 ’97 Conference. In January, 2000, the wiggler was transported to SPring-8, where the last test and measurements were carried out in collaboration with Japan. In this article, the results of measurements of the magnetic field, finding the magnetic field amplitude by an NMR probe, the definition of feed current relations by stretch current wire method, the calibration of a Hall probe in the high magnetic field, and the measurement of the magnetic field profile by a Hall probe are presented.
