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.…
