在JT-60 SA中采用反分析技术，高精度地重建了涡流产生的磁通量。该技术基于使用外部磁传感器信号的磁通量的重建，并且不需要预先精确定位导电结构。在导电结构的位置和形状不完全已知的情况下，成功地优化了等离子体击穿磁场。这种方法优化了逻辑击穿磁场，从而有效地减少了所需的时间，实现成功的击穿相比，传统的实验方法。
The magnetic fluxes generated by the eddy currents were reconstructed with high accuracy using an inverse analysis technique in JT-60SA. This technique is based on the reconstruction of the magnetic fluxes using the external magnetic sensor signals and does not require preliminarily the precise position of the conducting structures. The plasma breakdown magnetic field has been successfully optimized in a situation where the position and shape of the conducting structures were not exactly known. This method optimizes logically the breakdown magnetic field and thus reduces efficiently the time required to achieve successful breakdown compared to the conventional experimental approach.
