Automatic setting of machine control with physics operation parameters at ASDEX Upgrade

AbstractPerforming plasma fusion experiments in a tokamak relies on close cooperation between discharge control (DCS) and machine control (MCS) systems, where the DCS's task is generating and handling the plasma, and the MCS is responsible for providing and configuring the necessary actuators. With a reduced number of experiment cycles per day, in consequence of long pulses or ambitious discharge scenarios, optimal utilization of resources as well as avoiding mismatches between the MCS’ and DCS’ configurations becomes increasingly important. Setting up the MCS for discharges currently relies on informal communication and requires careful attention of operators and session leaders. To enforce correspondence between MCS and DCS parametrizations, an automatic mediator agent formalizes the pre-shot configuration procedure. Functionality of the mediator and protocols for embedding into the existing system are discussed.

トカマクにおけるプラズマ核融合実験の実施は、放電制御システム(DCS)と機器制御システム(MCS)との緊密な連携に依存している。ここで、DCSの役割はプラズマの生成と処理であり、MCSは必要なアクチュエータの提供と設定を担当する。長パルス運転シナリオや高度な実験シナリオにより1日あたりの実験サイクル数が減少する中、資源の最適利用とMCS・DCS設定間の不整合回避の重要性が増している。現在、放電実施のためのMCS設定は非公式なコミュニケーションに依存しており、運転員やセッションリーダーの細心の注意を要する。MCSとDCSのパラメータ設定間の対応関係を強化するため、自動仲介エージェントがショット前設定手順を形式化する。本仲介機能と既存システムへの組み込みのためのプロトコルについて議論する。
