Experimental verification of sawtooth control by energetic particles in ion cyclotron resonance heated JET tokamak plasmas

Experimental evidence from the JET tokamak is presented supporting the predictions of a recent theory (Graves et al 2009 Phys. Rev. Lett.102 065005) on sawtooth instability control by toroidally propagating ion cyclotron resonance waves. Novel experimental conditions minimized a possible alternate effect of magnetic shear modification by ion cyclotron current drive, and enabled the dependence of the new energetic ion mechanism to be tested over key variables. The results have favourable implications on sawtooth control by ion cyclotron resonance waves in a fusion reactor.

JETトカマクからの実験的証拠が提示され、鋸歯状不安定性制御に関する最近の理論(Graves et al 2009 Phys. Rev. Lett.102 065005)の予測を支持するものである。新規の実験条件により、イオンサイクロトロン電流駆動による磁気シア改変という可能性のある別の効果を最小化し、新たな高エネルギーイオンメカニズムの依存性を主要変数に対して試験することを可能にした。これらの結果は、核融合炉におけるイオンサイクロトロン共鳴波による鋸歯状制御に好ましい影響を与えるものである。
