Abstract

Analytic modeling tools have been developed to predict the quench behavior of the Superconducting Super Collider (SSC) dipole coils for a wide range of quench protection heater designs and configurations. Computer modeling tools have been developed to predict the time between heater firing and the initiation of conductor normal zones, and the maximum heater temperature for parametric variations in the heater strip geometry, resistance, material, protection circuit configuration, and conductor current and temperature. Verification of the modeling results has been accomplished by comparison of analysis results with data obtained from quench heater tests of DCA 311-321. Predictions for effective conductor enthalpy and time to normal zone initiation were found to correlate well with actual test data. Predictions have been made for the performance of heater designs for the GDSS prototype dipole magnets.<>
