PRODUCTION TECHNIQUES FOR THE SUPERCONDUCTING SUPER COLLIDER LOW-ENERGY BOOSTER QUADRUPOLE MAGNET

The manufacturing techniques used for a prototype quadrupole magnet, d eveloped at Lawrence Berkeley Laboratory (LBL) for the Superconducting Super Collider (SSC) Low Energy Booster (LEB), are described. The SSC LEB Ring employs % dipoles and 90 quadrupoles connected in series to form the magnetic lattice, requiring the use of a 21.9 mm x 23.0 mm ho llow conductor for the quadrupoles. Due to the large conductor size an d small bend radii required, development of special fixtures was neces sary. A unique coil-forming method with close attention paid to toolin g design and special assembly procedures was required to manufacture t his prototype to stringent specifications.
