Runaway electron behaviour during electron cyclotron resonance heating in the Frascati Tokamak Upgrade

The behaviour of high energy runaway electrons during the flat-top phase of electron cyclotron (EC) resonance heated (ECRH) discharges has been analysed in the Frascati Tokamak Upgrade. The decay of the electric field due to plasma heating has been observed to result in a rapid fall in the electron energy that frequently leads to quenching of the runaway population. The efficiency of this runaway mitigation scheme and its dependence on the plasma conditions has been investigated with particular emphasis on the required electric field drop during EC wave injection.

フラットトップ位相中の電子サイクロトロン(EC)共鳴加熱(ECRH)放電における高エネルギー逃走電子の挙動が、フラスカティ・トカマク・アップグレードにおいて解析された。プラズマ加熱による電場の減衰が、逃走電子集団の消滅を頻繁に引き起こす電子エネルギーの急速な低下をもたらすことが観測された。この逃走電子緩和の効率と、そのプラズマ条件への依存性が、特にEC波入射中の必要電場降下に焦点を当てて調査された。
