Solenoid-free current drive via ECRH in EXL-50 spherical torus plasmas
Yuejiang Shi, Bing Liu, Shaodong Song +25
As a new spherical tokamak (ST) designed to simplify engineering requirements of a possible future fusion power source, the EXL-50 experiment features a low aspect ratio (A) vacuum…
A new tool for two-dimensional field-reversed configuration equilibrium study
Haojie Ma, Huasheng Xie, Bihe Deng +7
A new tool (GSEQ-FRC) for solving two-dimensional (2D) equilibrium of field-reversed configuration (FRC) based on fixed boundary and free boundary conditions with external coils in…
Enhanced toroidal flow stabilization of edge localized modes with increased plasma density
Shikui Cheng, Ping Zhu, Debabrata Banerjee
Toroidal flow alone is generally thought to have important influence on tokamak edge pedestal stability, even though theory analysis often predicts merely a weak stabilizing effect…
Evaluation of ideal MHD mode stability of CFETR baseline scenario
Debabrata Banerjee, Ping Zhu, Shikui Cheng +4
The CFETR baseline scenario is based on a H-mode equilibrium with high pedestal and highly peaked edge bootstrap current, along with strong reverse shear in safety factor profile.…
Observation of whistler wave instability driven by temperature anisotropy of energetic electrons on EXL-50 spherical torus
Mingyuan Wang, Yuejiang Shi, Jiaqi Dong +19
Electromagnetic modes in the frequency range of 30-120MHz were observed in electron cyclotron wave (ECW) steady state plasmas on the ENN XuanLong-50 (EXL-50) spherical torus. These…
