Abstract :
Magnetic field measurements have been performed at Fermilab on 1.5 m magnetic length model dipoles for the Superconducting Supercollider (SSC). Harmonic measurements are recorded at room temperature before and after the collared cell is assembled into the yoke and at liquid helium temperature. Measurements are made as a function of longitudinal position and excitation current. High field data are compared with room temperature measurements of both the collared coil and the completed yoked magnet and with the predicted fields of both the body of the magnet and the coil ends. The effects of yoking and cold testing agree well with predictions. One of the two cold-tested dipoles satisfies the SSC specification for sextupole/decapole
