Non-Inductive Current Start-Up Using Multi-Harmonic Electron Cyclotron Wave and Current Ramp-Up Through Combined Electron Cyclotron Wave and Ohmic Heating in EXL-50U Spherical Torus
Xinchen Jiang, Yuejiang Shi, Yueng-Kay Martin Peng +21
The non-inductive current start-up by multi-harmonic electron cyclotron wave has been systematically investigated in the EXL-50U spherical torus. Significant enhancements of the dr…
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…
Overview of EXL-50 Research Progress and Future Plan
Yuejiang Shi, Yumin Wang, Bing Liu +37
XuanLong-50 (EXL-50) is the first medium-size spherical torus (ST) in China, with the toroidal field at major radius at 50 cm around 0.5T. CS-free and non-inductive current drive v…
