Experience in PF1 Dummy Pancake Manufacturing on the Mobile Facility for Winding and VPI of Large-Scale Superconductive Magnets

This paper describes the experience in PF1 dummy double pancake winding, which was performed in the Russian Federation in 2014-2015. The pancake was wound by the method of “two-in-hand” stress-free winding with continuous chemical cleaning and sandblasting of the conductor surface followed by application of multilayered turn insulation. The winding was accomplished by a mobile flexibly scalable complex of equipment installed within the shortest possible time in a special “clean room.” This complex has a number of advantages, such as mobility, cost effectiveness, independence, minimum attending personnel, synchronization of all operations under a unified automatic control system, continuous control, and possible fast correction of output parameters.
