Outline of Final Research Achievements

In these days, cyanate ester resins have been paid attention as an insulator for electromagnetic coils in accelerators having a higher radiation resistance than usual epoxy resins. In this study, we have succeeded in developing a cyanate-resin-made prepreg tape (glass fiber cloth impregnated with resin) and putty materials used for insulation of coil conductors. In addition, we have conducted a R&D to overcome the corrosion problem in conventional products of insulation tubes, which are required to separate water from an electric circuit at the end of the coil.
By these developments, we have established the manufacturing technology for new radiation-resistant magnet coils made of cyanate ester resins.
