Quench simulation studies of the TAC Jelly Roll superferric dipole corrector elements for the SSC

Using the computer program SSC-DTAC-T, which is a modification of the quench computer program SSC-RR, to model jelly roll coils, the quench behavior of the dipole corrector element (TAC design with jelly roll winding) is studied. The simulations are performed as a function of the length of the magnet, the copper to superconducting ratio, and the thickness of insulation surrounding the wires. The magnet is well self-protected under all of these considerations. In addition, this implies that the other corrector multipoles (quadrupole, sextupole, octupole, etc.) which use the same conductor winding technique are self-protected. A passive protection system is likely to work for these elements.<>
