在欧姆加热和辅助加热的JIPP T-IIU等离子体中进行了一系列初始共振螺旋偏滤器（RHD）实验。破坏性和MHD不稳定性的RHD结果的解释困难，但观察到的能量约束时间明显增加时，螺旋磁扰动。这可能是由于抑制了MHD活动或减少了边缘对流热损失。磁岛效应已被观察到的浮动电位的朗缪尔探针阵列和能量刮削层的宽度已被测量与没有螺旋扰动在ICRF操作。基本泵限制器的数据，包括离子温度和C4+杂质的配置文件。报告了欧姆和NBI加热放电中的能量约束时间。
A series of initial resonant helical divertor (RHD) experiments have been carried out in ohmically and auxiliary heated JIPP T-IIU plasmas. Disruptive and MHD instabilities make the interpretation of the RHD results difficult but an apparent increase in the energy confinement time is observed when the helical magnetic perturbation is applied. This may be due to the suppression of MHD activity or to a reduction in the edge convective heat losses. Magnetic island effects have been observed on the floating potential of a Langmuir probe array and energy scrape-off layer widths have been measured with and without helical perturbations during ICRF operation. Basic pump limiter data is presented including ion temperatures and C4+impurity profiles. Energy confinement times are reported in ohmically and NBI heated discharges.
