Re-acceleration of Energetic Ions via Small-Scale Reconnection in Magnetic Fusion Plasmas
Cong Zhang, Shaodong Song, Di Luo +15
We report the first observation on the EXL-50U spherical torus that energetic particles injected by neutral beam injection (NBI) can be stably accelerated to significantly higher e…

Achievement of 1 MA Discharges in Hydrogen-Boron Plasmas on EXL-50U
Yuejiang Shi
One mega ampere (MA) plasma discharges were achieved on the EXL-50U spherical torus (ST) in hydrogen-boron (p-B) plasmas with toroidal fields up to 1 T at major radii up to 0.6m. A…
