In the last two years, three major technical improvements have been made on J-TEXT in
supporting of the expanded operation regions and diagnostic capabilities.(1) The successful …

Disruption-generated runaway electron (RE) beams represent a potentially severe threat for
tokamak plasma-facing components. Application of properly designed 3D fields can act as a …

The runaway electrons (REs) during disruptions are a crucial problem, especially for the
future large-scale tokamaks, which is due to the local impact of RE beams and the large …

The main works on disruption mitigation including suppression and mitigation of runaway
current on the J-TEXT tokamak are summarized in this paper. Two strategies for the …

Runaway electrons represent a serious problem for the reliable operation of future
tokamaks. Radio frequency (RF) auxiliary heating can help suppress runaway electrons in …

Recently, experimental studies on the soft landing of RE current by ohmic (OH) field have
been performed in J-TEXT tokamak, as a possible auxiliary method to dissipate the RE …

Encapsulated payload pellet injection (EPPI) has been demonstrated to be an effective
method of disruption mitigation system (DMS) through a number of experiments and …

Plasma disruptions are one of the major challenges for the present tokamak devices and the
future ITER. REs generated in avalanche amplification are estimated to form up to 10 MA …
