Line identification of extreme ultraviolet spectra from aluminum ions in EAST Tokamak plasmas
Fengling Zhang, Ling Zhang, Wenming Zhang +13
Extreme ultraviolet (EUV) spectra emitted from aluminum in the 5-340 A wavelength range were observed in Experimental Advanced Superconducting Tokamak (EAST) discharges. Several sp…
A machine-learning-based tool for last closed-flux surface reconstruction on tokamaks
Chenguang Wan, Zhi Yu, Alessandro Pau +2
Nuclear fusion represents one of the best alternatives for a sustainable source of clean energy. Tokamaks allow to confine fusion plasma with magnetic fields and one of the main ch…
Experimental scaling of the scrape-off layer particle flux width by outboard divertor Langmuir probes with favorable Bt configuration on EAST
X. Liu, L. Y. Meng, J. C. Xu +3
The scrape-off layer (SOL) power width (λ_q) is important for predicting the heat load on divertor targets for future magnetically confined devices. Currently, the underlying physi…
A data management system for machine learning research of tokamak
Chenguang Wan, Zhi Yu, Xiaojuan Liu +3
In recent years, machine learning (ML) research methods have received increasing attention in the tokamak community. The conventional database (i.e., MDSplus for tokamak) of experi…
EAST discharge prediction without integrating simulation results
Chenguang Wan, Zhi Yu, Alessandro Pau +2
In this work, a purely data-driven discharge prediction model was developed and tested without integrating any data or results from simulations. The model was developed based on th…
Experiment data-driven modeling of tokamak discharge in EAST
Chenguang Wan, Jiangang Li, Zhi Yu +1
A model for tokamak discharge through deep learning has been done on a superconducting long-pulse tokamak (EAST). This model can use the control signals (i.e. Neutral Beam Injectio…
