The effects of field errors at the poloidal gap of the thick shell on the plasma performance and the wall-locking are intensively studied. The coil system of TPE-RX (major/minor radii, R/a= 1.72/0.45 m) has several features for cancelling the field errors at the thick shell gap and for controlling the equilibrium position of the plasma column. It is confirmed that these field error cancellation schemes work well for the normal operating conditions in TPE-RX. It is shown quantitatively that the global performance of the revised-field pinch operation is affected if the shell gap field error exceeds about 5% of the poloidal magnetic field. As expected, the probability of the mode to lock at the shell gap increases as the field error increases.

厚肉シェルのポロイダルギャップにおける磁場誤差がプラズマ性能とウォールロッキングに及ぼす影響について集中的に研究した。TPE-RX(主半径/副半径、R/a= 1.72/0.45 m)のコイルシステムは、厚肉シェルのギャップにおける磁場誤差を打ち消し、プラズマ柱の平衡位置を制御するためのいくつかの特徴を有している。これらの磁場誤差補正方式がTPE-RXの通常運転条件下で良好に機能することが確認された。シェルギャップの磁場誤差がポロイダル磁場の約5%を超えると、改訂された磁場ピンチ運転の全体性能が影響を受けることが定量的に示された。予想通り、磁場誤差が増加するにつれて、シェルギャップでのモードロッキングの確率が増加する。
