Slow External Beam Ejection Magnets and Power Supplies

Detailed electrical and mechanical parameters and design is given for thin septum type magnets and supplies required in the final step of the slow extracted beam in the 30 GeV Alternating Gradient Synchrotron at Brookhaven National Laboratory. Thermal considerations for both magnets and power supplies are of prime importance. Primary and secondary protection schemes are described. Radiation hardening of the magnet components is greatly emphasized due to the expected severe radiation damage on these components.
