• The detailed design for the construction of the Q2/Q3 quadrupole magnets for CEBAF's Resolution Spectrometers is presented. The quadrupoles have a warm bore diameter of 600 mm and a cryostat length of 3 m. The quadrupole coil will be wound from a cable conductor carrying a current of 1850 A, the field gradient is 3.5 T/m. A set of eight superconducting multipole coils is positioned in the helium vessel within the bore of the main coil. Each multipole coil is supplied by a separate current lead. The cold mass is suspended by eight support rods of titanium, sized for a static load of 3 g omnidirectionally, which are fixed at the iron yoke tube surrounding the magnet cryostat. Cold alignment of the quadrupole coil relative to the iron yoke is possible via these supports. The detailed design of the quadrupole coil, the multipole coils, the current leads, the cryostat and of the iron yoke is described.< >
