Title: Tests of insulation systems for Nb3Sn wind and react coils

Journal Article ·
OSTI ID:919075

Tests were performed to assess the viability of several cable insulation systems for use in Nb{sub 3}Sn accelerator magnets. Insulated stacks of cables were subjected to reaction cycles commonly used for Nb{sub 3}Sn 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 500V. 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.
