Note b: Preliminary quantity of 2 TH and 2 TV coils would be ordered as part of an engineering verification unit. 5 Fabrication and Material Requirements 5.1 Quadrupole & Sextupole Magnet Coils The quadrupole magnet coils shall be Oxygen-Free High Conductivity (OFHC) copper coils. The coils shall be electrically insulated turn to turn and coil to ground with a fiberglass/vacuum impregnated epoxy system as described herein. The Contractor is responsible for designing and fabricating all the tooling necessary and developing the methods needed to consistently wind the coils and to install the water fittings and plugs. 5.1.1 Copper Conductor The quadrupole coil conductors shall be hollow oxygen-free electrolytic copper (OFHC), with an annealed electrical conductivity of 101% of IACS 20C in accordance with ASTM-B170-99. The quadrupole coil conductor cross-section and centered water-cooling hole shall be as defined in Table 4-1, and the corrector coil wire gauge size shall be as defined in Table 4-2 for the respective magnets. 5.1.2 Water Fittings The quadrupole and sextupole magnet copper coils shall use threaded stainless-steel pipe thread fittings brazed into the copper coil ends or sides near the coil ends. The fittings shall be brazed with a braze metal alloy and flux specific to copper to stainless steel joints. 5.1.3 Coil Electrical Insulation The turn-to-turn insulation shall consist of glass fiber tape, amino-silane treated pure E-glass tape or approved equivalent, half-lap wound during the coil winding process. The final wrapped turn- to-turn tape insulation shall be a minimum of 0.5 mm (0.020") thick. The completed wound coil shall have an additional outer wrapping of glass fiber tape, amino- silane treated pure E-glass tape or app…
