Heater induced quenches in SSC model dipoles

A 1-m long SSC dipole constructed at the Lawrence Berkeley Laboratory was subjected to a series of heater induced quenches to determine: axial quench propagation velocities, transverse quench propagation, and conductor temperature rise. Quenches were produced by 3 heaters at different locations in the magnet and at several currents. The results of these studies are described and are compared to previously published theoretical studies of quenches on the SSC dipoles. These results are shown to be in agreement with the calculations of the program "QUENCH", which includes an increase of the quench velocity during the first few milliseconds of the quench.
