Investigation of the effectiveness of non-inductive `multi-harmonic' electron cyclotron current drive through modeling multi-pass absorptions in the EXL-50 spherical tokamak
D. Banerjee, S. D. Song, H. S. Xie +14
The effectiveness of multiple electron cyclotron resonance (ECR) harmonics has been thoroughly investigated in context of high current drive efficiency, generally observed in fully…
Observation of a strong correlation between the positive floating potential near the edge and plasma current on EXL-50 ECW plasma
Mingyuan Wang, Dong Guo, Xin Zhao +12
Fully non-inductive plasma current start-up without the central solenoid in ECW plasma was used on EXL-50 Spherical Torus with a weak external vertical field (Bv). Generally, the n…
Non-inductive plasma current sustainment with stochastic electron cyclotron in EXL-50 spherical torus
Mingyuan Wang, Shikui Cheng, Bing Liu +11
The start-up and sustainment of a stochastic wave non-inductive current on a spherical torus was experimentally demonstrated for the first time using only electron cyclotron waves.…
Low- global ideal MHD instabilities in CFETR baseline scenario
Rui Han, Ping Zhu, Debabrata Banerjee +3
This article reports an evaluation on the linear ideal magnetohydrodynamic (MHD) stability of the China Fusion Engineering Test Reactor (CFETR) baseline scenario for various first-…
Stabilizing effect of enhanced resistivity on peeling-ballooning instabilities on EAST
Xin Lin, Debabrata Banerjee, Ping Zhu +6
Previous stability analysis of NSTX equilibrium with lithium-conditioning demonstrates that the enhanced resistivity due to the increased effective charge number Zeff (i.e. increas…
MHD stability analysis of ideal wall modes for CFETR upgrade phase-I scenario using NIMROD
Shikui Cheng, Ping Zhu, Debabrata Banerjee +1
Ideal MHD stability of China Fusion Engineering Test Reactor (CFETR) upgrade phase-I baseline scenario has been evaluated using the initial value code NIMROD. The toroidal mode num…
