Resolutions of Problems that Occurred in Spear3 Magnet Production

Some problems occurred during the SPEAR3 magnet production at IHEP, China. It was very hard to find resolution from existing knowledge of those problems. It was possible that similar problems might have happen in building accelerator magnet in other institutes before, but they were not addressed in public papers. These problems were discussed and solved by engineers from both SLAC and IHEP after conducting certain experiments. Traditionally, the magnet design and measurement data have been always well documented and addressed in papers, but the production experiences have not been recorded adequately. It is the goal of this paper to record the problems and their resolutions during SPEAR3 magnet production at IHEP China, which will certainly benefit future magnet projects.
