Experimental investigation of kinetic instabilities driven by runaway electrons in the EXL-50 spherical torus
Mingyuan Wang, Mingsheng Tan, Yuejiang Shi +8
In this study, the first observation of high-frequency instabilities driven by runaway electrons has been reported in the EXL-50 spherical torus using a high-frequency magnetic pic…
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…
First Identification of New X-Ray Spectra of Mo39+, Mo40+, W43+, W44+ and W45+ on EAST
Fudi Wang, Dian Lu, Mingfeng Gu +27
New high-resolution x-ray spectra of Mo39+, Mo40+, W43+, W44+ and W45+ have been carefully confirmed for the first time by use of the x-ray imaging crystal spectrometer (XCS) in Ex…
Experimental study on edge energetic electrons in EXL-50 spherical torus
Dong Guo, Yuejiang Shi, Wenjun Liu +9
A significant number of confined energetic electrons have been observed outside the Last Closed Flux Surface (LCFS) of the solenoid-free, ECRH sustained plasmas in the EXL-50 spher…
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.…
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…
Dynamics of cold pulses induced by super-sonic molecular beam injection in the EAST tokamak
Yong Liu, Yuejiang Shi, Tao Zhang +9
Evolution of electron temperature, electron density and its fluctuation with high spatial and temporal resolutions are presented for the cold pulse propagation induced by super-son…
Observation of non-local effects in ion transport channel in J-TEXT plasmas
Yuejiang Shi
In cold pulse experiments in J-TEXT, the ion transport shows similar non-local response as the electron transport channel. Very fast ion temperatures decreases are observed in the…
Alternating Current Adiabatic Compression Tokamak: A New Way to Fusion Reactor
Yuejiang Shi
A novel magnetic confined fusion scheme for the fusion reactor is proposed in this paper. A simple numerical estimation shows that ignition of D-T plasma can be achieved in tokamak…
New experimental findings of non-local transport in J-TEXT plasmas
Yuejiang Shi
In the cold pulse experiments in J-TEXT, not only are the rapid electron temperature increases in core observed, but also the steep rises of inner density are found. Moreover, the…
Fluctuation signatures of rotation reversals and non-local transport events in KSTAR L-mode plasmas
Yuejiang Shi
Experiments of electron cyclotron resonance heating (ECH) power scan in KSTAR tokamak clearly demonstrate that both the cut-off density for non-local heat transport (NLT) and the t…
Investigation of toroidal acceleration and potential acceleration forces in EAST and J-TEXT plasmas
Fudi Wang, Bo Lyu, Xiayun Pan +18
In order to produce intrinsic rotation, bulk plasmas must be collectively accelerated by the net force exerted on them, which results from both driving and damping forces. So, to s…
