Tests were performed to assess the viability of several cable insulation systems for use in Nb3Sn accelerator magnets. Insulated stacks of cables were subjected to reaction cycles commonly used for Nb3Sn coils. After reaction and epoxy impregnation, current leakage between turns was measured at pressures up to 180 MPa and turn‐to‐turn potentials up to 500 V. Systems consisting of S‐2 glass, ceramic fiber, and E‐glass were tested. Several methods of applying the insulation were incorporated, including sleeves and various spiral wrapped configurations. Methods of sample preparation and testing are described and results are reported.
