在1993年至1997年的DT运行期间，在TFTR上进行了α粒子物理实验。这些实验利用了几种新的α粒子诊断和数百次DT放电来表征α粒子约束和波粒相互作用。总的来说，α粒子诊断的结果与经典的单粒子约束模型在MHD静态放电。在某些情况下，由于环形场涟漪的α损失被确定，并推断高能量α的低径向扩散率是一致的轨道平均在小尺度湍流。最后，所观察到的α粒子与锯齿，环形阿尔芬本征模和ICRF波的相互作用与理论模型大致一致。对所学内容进行了回顾，并确定了仍需理解的内容。
Alpha particle physics experiments were done on TFTR during its DT run from 1993 to 1997. These experiments utilized several new alpha particle diagnostics and hundreds of DT discharges to characterize the alpha particle confinement and wave-particle interactions. In general, the results from the alpha particle diagnostics agreed with the classical single particle confinement model in MHD quiescent discharges. The alpha loss due to toroidal field ripple was identified in some cases, and the low radial diffusivity inferred for high energy alphas was consistent with orbit averaging over small scale turbulence. Finally, the observed alpha particle interactions with sawteeth, toroidal Alfven eigenmodes and ICRF waves were approximately consistent with theoretical modelling. What was learned is reviewed and what remains to be understood is identified.
