Insulation is one of the critical components for high-field Nb3Sn magnets that follow wind-and-react approach. The insulation material has to withstand high bending stresses while winding the coil and high heat-treatment temperatures under pressure during coil reaction. At Fermilab we have developed a procedure and tested successfully the dry ceramic insulation tape with inorganic liquid binder to wind and cure the coils. Recently we have extended this to a pre-preg ceramic insulation tape, which would minimize and control the amount of binder in the coil. Several coils with various insulation patterns have been fabricated and tested at Fermilab. This paper discusses the fabrication issues of the coils with different types of cable insulation including the pre-preg ceramic insulation.
