Quench and quench protection for the SSC collider correctors
The quench voltage, especially the turn-to-turn voltage, and the maximal temperature rise due to the quench in 50-mm-aperture Superconducting Super Collider correctors are calculated for various currents. The calculation shows a lower copper-to-superconductor ratio gives a lower quench voltage and a lower temperature rise as the result of much higher heat capacity of the superconducting material and lower copperresistivity at lower temperature. It also shows that when the copper to superconductor ratio is 2.2 to 1, each individually powered magnet is self-protected, and for the series of 24 correctors that are poweredtogether in the collider, a parallel 2-O resistor on each magnet will provide needed protection. The energy loss on these resistors during powering up is less than 5% of the energy stored in the magnet at the operating current.
