Summary

A superconducting model rotor had been constructed and a pair of test coil in the rotor was replaced after the preliminary test. The normal zone propagating velocities and the minimum propagating current were measured on this new test coil. These experimental results were compared with the calculated results by Dresner's equation. The rotation speed dependence was measured and the experimental results were well explained theoretically by Dresner's equation. The normal zone propagating velocities at the downward of helium flow were measured and the temperature rise of the conductor due to hot helium flow from upward were found out.
