A new type of spontaneous formation of plasmoid is observed in our toroidal plasma merging experiment on TS‐6 using a newly developed high‐resolution magnetic probe array, which has axially gyro‐scale spatial resolution (ΔZ ∼ 1.1 cm). In the axially elongated new machine, the plasmoid is formed near the mid‐plane with a configuration of two X‐points in the early phase of magnetic reconnection when the initial two flux tubes (merging tokamaks) are still in their respective formation region. The plasmoid is then merged with the major upstream plasmas at the two X‐points, which finally triggers the increment of reconnection speed. © 2020 Institute of Electrical Engineers of Japan.

在两个合并的托卡马克的早期磁重连接阶段中类固醇的自发形成

一种新型的自发形成等离子体团的的是在我们的环形等离子体合并实验中观察到的TS-6采用新开发的高分辨率磁探针阵列，其具有沿轴向尺度陀螺空间分辨率（在Δ Ž 〜 1.1厘米）。在轴向拉长的新机器中，当最初的两个通量管（合并的托卡马克）仍位于其各自的形成区域时，在磁重连接的早期，等离子体在中平面附近形成，并具有两个X点的配置。然后，等离子体在两个X点与主要的上游等离子体合并，最终触发重新连接速度的增加。©2020日本电气工程师学会。由Wiley Periodicals LLC发布。
