等离子体实验装置S-RT（超导环阱）计划用于东京大学的高β等离子体约束研究。作为前一步，Mini-RT是S-RT的缩小版，已作为NIFS，东京大学和九州大学的联合研究而构建。在本实验中，磁悬浮线圈（浮动线圈）在持续电流模式下工作，必须在等离子体真空容器中悬浮8小时。用Bi-2223带缠绕的HTS浮动线圈具有300 mm的直径和50 kA的电动势。由于在等离子体实验期间不能向线圈供给任何制冷剂，因此线圈被设计成使得在悬浮8小时之后，线圈和辐射屏蔽的比热的温度升高小于40 K。在每天的等离子体实验结束时，线圈将被拉到等离子体真空容器底部的维护位置，并将重新冷却到20 K。
The plasma experiment apparatus S-RT (Superconducting Ring Trap) is planned for the purpose of high beta plasma confinement research in the University of Tokyo. As a preceding step, Mini-RT, which is the size reduction version of S-RT, has been constructed as a joint research of NIFS, the University of Tokyo, and Kyushu University. In this experiment a magnetic-levitation coil (floating coil) operated in persistent current mode has to levitate for 8 hours in the plasma vacuum vessel. The HTS floating coil wound with a Bi-2223 tape has a diameter of 300 mm and an electromotive force of 50 kA. Since any refrigerant cannot be fed to the coil during the plasma experiment, the coil is designed so that the temperature rise after 8 hours of levitation is less than 40 K with the specific heat of the coil and radiation shield. At the end of the daily plasma experiment, the coil will be drawn down to the maintenance location at the bottom of the plasma vacuum vessel, and it will be re-cooled to 20 K.
