Studies on plasma confinement and wall interaction (conditioning, pump limiter and movable limiter) in addition to the helicity injection have been done in a reversed field pinch device.Energy confinement is governed by the magnetic fluctuations, and MHD dynamo sustains the poloidal current inside the reversal surface and transport of fast electrons is more important in edge plasma region.By the use of He glow, hydrogen glow, carbonization and boronization, improvements of plasma parameters have been found. Increase in loop voltage by inserting a movable limiter can be explained by the Spitzer term. First trial of helicity injection has been done. Plasma takes more relaxd state locally after this helicity injection. Induced voltage is influenced by the presence of fast electrons.

除螺旋注射外，还进行了有关血浆限制和壁相互作用（调节，泵限限和可移动限制）的研究，在反向的野外夹具装置中进行。能源限制受磁波动的控制，MHD Dyn​​amo维持了在边缘的电流和快速电子区域内的Poloid Proloid电流，并且在Edge Edde Edge plog and Flof and Plow and plow and plow she gl of the He gl of the He gl of the He gl of the He gl of the He gl of the He glof the He gl of the He glof the He gl of。硼化，血浆参数的改进。通过插入可移动限制器的循环电压增加可以通过Spitzer项来解释。已经进行了螺旋性注射的首次试验。在这种螺旋性注射后，血浆在本地采取更多松弛状态。诱导电压受到快速电子的存在的影响。
