已经为 Elmo Bumpy Torus 开发了基于重离子束探针技术的诊断系统。多种单电荷碱金属离子已用于探测束；多电荷反应产物的检测允许对等离子体空间电势进行连续的空间分辨监测。典型的空间分辨率为1 cm−3；时间分辨率约为1秒。电位测量是直接的并且正确地参考等离子体接地。对测量中可能的误差来源的调查得出的结论是，不确定性比实验测量的电势小一个数量级。
A diagnostic system based on the heavy ion beam probe technique has been developed for the Elmo Bumpy Torus. A variety of singly charged alkali metal ions have been used in the probing beam; detection of multiply charged reaction products allows a continuous spatially resolved monitor of the plasma space potential. Typical spatial resolution is 1 cm−3; time resolution is on the order of 1 s. The potential measurement is direct and properly referenced to the plasma ground. An investigation into possible sources of error in the measurement points to the conclusion that the uncertainty is an order of magnitude less than the experimentally measured potentials.
