Developments in the real time control hardware on Tokamak à Configuration Variable (TCV) coupled with the flexibility of plasma shaping and electron cyclotron (EC) heating and current drive actuators are opening many opportunities to perform real time experiments and develop algorithms and methods for fusion applications. The ability to control magnetohydrodynamic instabilities is particularly important for achieving high performance fusion plasmas and EC is envisaged as a key actuator in maintaining high performance. We have successfully demonstrated control of the sawtooth instability using the EC launcher injection angle to modify the current profile around the q =1 surface. This paper presents an overview of recent real time control experiments on TCV, developments in the hardware and algorithms together with plans for the future.

TCV(Tokamak à Configuration Variable)におけるリアルタイム制御ハードウェアの開発は、プラズマ形状の柔軟性および電子サイクロトロン(EC)加熱・電流駆動アクチュエータと相まって、核融合応用のためのリアルタイム実験の実施とアルゴリズム・手法の開発における多くの機会を開いている。磁気流体力学的不安定性を制御する能力は、高性能核融合プラズマを達成するために特に重要であり、ECは高性能を維持する上での主要なアクチュエータとして想定されている。我々は、ECランチャーの入射角度を用いてq = 1 面周辺の電流分布を変更することにより、鋸歯状不安定性の制御を実証することに成功した。本論文は、TCVにおける最近のリアルタイム制御実験、ハードウェアとアルゴリズムの開発、および将来の計画の概要を提示する。
