Private data, when published online, may be collected by unauthorized parties to train deep neural networks (DNNs). To protect privacy, defensive noises can added original samples degrade their learnability DNNs. Recently, unlearnable examples are proposed minimize the training loss such that model learns almost nothing. However, raw data often pre-processed before being used for training, which restore private information of protected data. In this paper, we reveal privacy violation induced...
An accurate evolution model is crucial for effective control and in-depth study of fusion plasmas. Evolution methods based on physical models often encounter challenges such as insufficient robustness or excessive computational costs. Given the proven strong fitting capabilities deep learning across various fields, including plasma research, this paper introduces a learning-based magnetic measurement method named PaMMA-Net (Plasma Magnetic Measurements Incremental Accumulative Prediction...
Biological responses to climate and environmental changes in remote polar regions are of increasing interest global change research. Terrestrial marine ecosystems have suffered from impacts both rapid intense human activities, large fluctuations the population sizes seabirds, seals, Antarctic krill been observed past decades. To understand mechanisms driving these regime shifts ecosystems, it is important first distinguish influences natural forcing anthropogenic activities. Therefore,...
P-EFIT, a GPU parallel equilibrium reconstruction code, is based on the EFIT framework, but built with CUDA™ (Compute Unified Device Architecture) to take advantage of massively Graphical Processing Unit (GPU) cores significantly accelerate computation. With parallelized Grad-Shafranov solver and middle-scale matrix calculation modules, P-EFIT can accurately reproduce algorithms at fraction computational time. Integrated into EAST plasma control system, not only provides signal results also...
Abstract Plasma equilibrium is critical for experimental operation and data analysis in tokamaks. The number location of magnetic diagnostics provide the field flux information that influences accuracy plasma reconstruction.

This implies...
In order to measure controllability of vertical instability in EAST, the calculation model-based growth rate, called rt-gamma, has been successfully carried out real time. The numerical computing method is adapted from rigid plasma response model TokSys, which a widely-used analysis tool for tokamak devices Matlab environment, but code rewritten by taking advantage GPU parallel capability accelerate computation. rt-gamma validated comparing it with corresponding result generated TokSys...
The efficient and safe operation of large fusion devices strongly relies on the plasma configuration inside vacuum chamber. It is important to construct proper equilibrium with a desired configuration. In order target configuration, shape constraint module has been developed in tokamak simulation code (TSC), which controls poloidal flux magnetic field at several defined control points. used double null, lower single quasi-snowflake configurations for required calculate PF coils current....
Abstract An advanced plasma current tomography method is established for the Experimental Advanced Superconducting Tokamak (EAST), which combines Bayesian probability theory and neural networks. It different from existing based on a conditional autoregressive (CAR) prior. Specifically, CAR prior replaced with an squared exponential (ASE) kernel function Therefore, proposed can overcome deficiencies of prior, where calculated core lower than reference uncertainty becomes severe after...
Vertical displacement event (VDE) is a big challenge to the existing tokamak equipment and that being designed. As Chinese next-step tokamak, Fusion Engineering Test Reactor (CFETR) has pay attention VDE study with full-fledged numerical codes during its conceptual design.

Abstract In 2021, EAST was equipped with a full-ring divertor coil to facilitate research on the fish tail concept. Initially, it observed that current had negligible ability sweep strike point. Conversely, when amplitude and frequency of alternating were marginally increased, there significant interruption plasma control. This perturbation attributed poloidal control field’s limited response rate coil’s fluctuations. To address this issue, novel methodologies devised ensure stable effective...
