“…This essentially ruled out the use of magnesium-oxide or mineral insulated (MI) conductor sine* its poor packing factor (32 to 46Z) would require the coll to grow significantly to provide the original number oC amp-turns.12] colls and developed coils wound from aluminum conductors whose surface was hard anodized to provide electrical insulation. [3] This proved to be a successful approach and, following their use at Nevis, four quadrupoles of this design were brought to Brookhaven and have run without problems in the AGS Experimental Areas for over three years. Aluminum conductors were considered for the replacement coils, however, they were judged to be unsuitable since they could not support the 59 A/mm 2 current density existing in the present colls.…”

A C-type septum dipole magnet Is located 600 mm downstream of the prisary target In an external beam line of the ACS. Conventional use of fiber glass/ epoxy electrical insulation for the magnet coils results in their failure after a relatively short running period, therefore a r&dlatlon hard Insulation system is required. This Is accomplished by replacing the existing copier conductor with a copper conductor having a chin aluminum skin which is anodized to provide the electrical insulation. Since the copper supports a current density of 59 A/an 2 , no reduction in cross sectional area can be tolerated. Design considerations, Manufacturing techniques, and operating experience of a prototype dipole is presented.
