Recent control advances at KSTAR enabled us to not only establish but also to sustain the ITER-similar shape (ISS) in a stationary manner, matching the ITER-like dimensionless shape parameters in lower single null configuration with vastly contrasting upper/lower triangularities. The kinetic parameters of the ISS are different from the typical KSTAR configurations seen in ELM-RMP suppression experiments. We experimentally demonstrate the ISS-compatible resonant magnetic perturbation (RMP) control in KSTAR for the first time, using the n = 2, +90 degrees phasing RMP.

KSTARにおける最近の制御の進展により、ITER類似形状(ISS)を定常的に確立・維持することが可能となった。これは、上部と下部の三角変形量が大きく異なる下部単一ヌル配位において、ITER類似の無次元形状パラメータを一致させるものである。ISSの運動論的パラメータは、ELM-RMP抑制実験で見られる典型的なKSTAR配位とは異なる。我々は、n = 2、+90度位相のRMPを用いて、KSTARにおけるISS適合型共鳴磁気摂動(RMP)制御を初めて実験的に実証した。
