中空導体を用いた超電導電磁石の実験

抄録

This paper reports the experimental results of the hollow superconducting magnet on which the author worked at Saclay, France.
The race track coil was chosen for the experimantal set-up. The distribution of magnetic field was stricktly calculated. The circuit for supercritic helium was explained. The current density of 7, 000A/cm² in the hollow conductor could be obtained with the maximum magnetic field of 34KG and the stored energy of 40kj. The flow rate, the pressure drop and the temperature rise were measued and will serve for future design. The author acknowleges for his stay at Saclay.
