Method for measuring divertor configuration parameters for feedback control in JT–60

A new method for measuring divertor configuration parameters (plasma position, location of separatrix surface, βp + ℓi/2) for feedback control in JT-60 is presented. By using the MHD equilibrium database, it is possible to derive statistical relations expressed by simple functions between these parameters and the measured values of quantities such as poloidal magnetic fields, plasma current and external coil currents. These functions can be used as the measurement formulas of these parameters. In JT-60, the second order polynomial functions of these magnetically measured values, which are obtained as the measurement formulas, are sufficiently accurate to be applicable to feedback control.

ダイバータ配位パラメータ(プラズマ位置、セパラトリックス表面の位置、βp+ℓi/2)をJT-60におけるフィードバック制御のために測定する新しい方法を提示する。MHD平衡データベースを用いることにより、これらのパラメータと、ポロイダル磁場、プラズマ電流、外部コイル電流などの測定値との間の統計的関係を、単純な関数で表すことが可能となる。これらの関数は、これらのパラメータの測定式として使用できる。JT-60においては、これらの磁気測定値の二次多項式関数として得られる測定式は、フィードバック制御に適用可能な十分な精度を有する。
