High-frequency heating experiments in PETULA and WEGA tokamaks

The feasibility of two RF heating schemes, Transit Time Magnetic Pumping and Lower Hybrid heating, has been tested at the Grenoble Laboratory. TTMP results on PETULA were accurately consistent with theory; power absorption was only limited by the unfavourable scaling for small devices. – Launching of lower hybrid waves was made convenient by the grill concept. WEGA and PETULA B experiments showed that ions can be efficiently heated and interaction with electrons leads to non-inductive current drive. Tokamak discharges for which the current is entirely or mainly supported by waves have good confinement and stability properties.

2つのRF加熱方式、すなわち走行時間磁気ポンピング(TTMP)と低混成波加熱の実現可能性が、グルノーブル研究所で試験された。PETULAにおけるTTMPの結果は理論と正確に一致した。出力吸収は、小型装置にとって不利なスケーリング則によってのみ制限された。– 低混成波の励起は、グリル概念によって容易になった。WEGAおよびPETULA Bの実験は、イオンが効率的に加熱され得ること、そして電子との相互作用が非誘導電流駆動をもたらすことを示した。電流が完全にまたは主に波動によって維持されるトカマク放電は、優れた閉じ込め特性と安定性特性を有する。
