为了测量大型螺旋装置 (LHD) 的潜力，我们一直在开发重离子束探针 (HIBP)。探测束采用金束，由串联加速器加速至6 MeV能量。进行了束流轨道标定实验，并将实验结果与轨道计算结果进行了比较。实验结果与计算结果基本吻合。束流轨道校准后，尝试用 HIBP 测量等离子体中的电位。实验数据显示，在 ne ∼ 5 × 1018 m-3 的条件下，中性束加热阶段出现正电势，并且当对该等离子体施加额外的电子回旋加热时，观察到电势的增加。这种增加的时间常数约为几十毫秒，这比理论预期要大。在样本体积的空间位置上，我们在这个实验中可能存在模糊性。
In order to measure the potential in Large Helical Device (LHD), we have been developing a heavy ion beam probe (HIBP). For probing beam, gold beam is used, which is accelerated by a tandem accelerator up to the energy of 6 MeV. The experiments for calibration of beam orbit were done, and experimental results were compared with orbit calculations. The experimental results coincided fairly with the calculation results. After the calibration of the beam orbit, the potential in plasma was tried to measure with the HIBP. The experimental data showed positive potential in a neutral beam heating phase on the condition of ne ∼ 5 × 1018 m-3, and the increase of potential was observed when the additional electron cyclotron heating was applied to this plasma. The time constant for this increase was about a few tens ms, which was larger than a theoretical expectation. In the spatial position of sample volume, we might have an ambiguity in this experiment.
