金中性光束探头用于确定 GAMMA 10 串联镜的热障单元和中心单元处的空间电势。热障电势是通过同时测量两个位置的轴上空间电势来确定的。通过使用不同光束能量扫描探测光束来测量障碍物横截面上的等势线。在低密度实验的情况下，GAMMA 10 研究了与二维空间势分布相关的热障深度和新古典径向离子输运的增强。
Gold neutral beam probes are used for the determination of the space potentials at the thermal barrier cells and the central cell of the GAMMA 10 tandem mirror. The thermal barrier potential is determined by simultaneous measurements of the on-axis space potentials at both locations. Equipotential contours over a cross-section at the barrier are measured by sweeping the probing beams with different beam energies. The enhancement of the thermal barrier depth and of the neoclassical radial ion transport in relation with two-dimensional space potential profiles has been studied in GAMMA 10 for the case of low density experiments.
