Curing of LHC Main Dipole Coils Insulated with all Polyimide PIXEO¯ Adhesive Tape

An all polyimide system made by plain and adhesive coated tapes has been adopted for the insulation of the LHC coils. In this analysis we put in evidence how different parameters in the curing cycles could affect the final bonding quality. Data for two different glue compositions are compared showing how the conjoint efforts of CERN and tape supplier Kaneka High-Tech Materials has helped to enlarge the window in which this material provides outstanding gluing, making easier to keep under control bonding quality throughout the mass production in a real industrial environment
