IDP-PGFE: an interpretable disruption predictor based on physics-guided feature extraction

Nuclear Fusion, 2023
Disruption prediction has made rapid progress in recent years, especially in machine learning (ML)-based methods. If a disruption prediction model can be interpreted, it can tell why certain samples are classified as disruption precursors. This allows us

Development and large volume production of extremely high current density YBa2Cu3O7 superconducting wires for fusion

Scientific Reports, 2021
The fusion power density produced in a tokamak is proportional to its magnetic field strength to the fourth power. Second-generation high temperature superconductor (2G HTS) wires demonstrate remarkable engineering current density (averaged over the full

Fundamentals of Plasma-Material Interactions in Magnetic Fusion Devices

Plasma Science and Technology, 2018
The interaction of plasmas and materials has a long history in the modification of con- densed matter. Plasma-material interaction (PMI) can govern how low-temperature and high-temperature plasmas interact and modify materials surfaces.

Disruption prediction for future tokamaks using parameter-based transfer learning

Communications Physics, 2023
Tokamaks are the most promising way for nuclear fusion reactors. Disruption in tokamaks is a violent event that terminates a confined plasma and causes unacceptable damage to the device.
