DEVICE FOR MONITORING SUPERCONDUCTIVE COIL FOR AC

摘要

PURPOSE:To enable an AC loss and an operation state of a superconductive coil to be monitored stably. CONSTITUTION:A superconductive coil 12 is formed by a compound cable 11 where a plurality of superconductive element wires 11a and a plurality of insulation film conductors are twisted, a superconductive element wire and an insulation film conductor are connected at one edge side of the coil, and at the same time a detector 14 is connected through an amplifier 13, thus enabling a space between the superconductive element wire and a measurement wire to be eliminated and preventing increase in noise.
