Abstract :
Tests have been performed at Fermilab on 1.5-m magnetic length model SSC (Superconducting Super Collider) dipoles using both bipolar and unipolar ramp cycles. Hysteresis energy loss due to superconductor and iron magnetization and eddy currents is measured and compared as a function of various ramp parameters. Additionally, magnetic field measurements have been performed for both unipolar and bipolar ramp cycles. Measurements such as these will be used to estimate the heat load during collider injection for the SCC High Energy Booster dipoles.<>
