This chapter describes the experimental results for the fabricated magnet. The magnet was operated in a conduction cooling environment and achieved the target central magnetic field. However, the measured magnetic field uniformity was lower than the designed value. This issue appears to result from shape deviations during fabrication, measurement errors, and screening current. Additionally, the temporal stability of the magnetic field under sustained current in driven-mode operation was examined. To improve magnetic field uniformity, a ferroshim was designed and fabricated, and measurements confirmed an improvement in uniformity.

摘要

This chapter describes the experimental results for the fabricated magnet. The magnet was operated in a conduction cooling environment and achieved the target central magnetic field. However, the measured magnetic field uniformity was lower than the designed value. This issue appears to result from shape deviations during fabrication, measurement errors, and screening current. Additionally, the temporal stability of the magnetic field under sustained current in driven-mode operation was examined. To improve magnetic field uniformity, a ferroshim was designed and fabricated, and measurements confirmed an improvement in uniformity.
