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…

EFIT-mini: An Embedded, Multi-task Neural Network-driven Equilibrium Inversion Algorithm
Guohui Zheng, Songfen Liu, Huasheng Xie +11
Equilibrium reconstruction, which infers internal magnetic fields, plasmas current, and pressure distributions in tokamaks using diagnostic and coil current data, is crucial for co…
