Investigation of the Water Draining Process Pushed by Gas for U‐Type and Z‐Type Manifolds

Science and Technology of Nuclear Installations, Volume 2022, Issue 1, 2022., 2022
In the experimental advanced superconducting tokamak (EAST), the cooling channels of plasma‐facing components (PFCs) are familiarly connected in parallel through manifolds. According to the drainage performance of the PFCs, the amount of water trapped in the cooling channels is directly correlated with the type of manifolds.

A machine-learning-based tool for last closed-flux surface reconstruction on tokamaks

Nuclear Fusion, 2023
Tokamaks allow to confine fusion plasma with magnetic fields. The prediction/reconstruction of the last closed-flux surface (LCFS) is one of the primary challenges in the control of the magnetic configuration.

Observation of electrostatic fluctuations driven by runaway electrons in EAST disruptions

Nuclear Fusion, 2023
Electrostatic fluctuations driven by runaway electrons (REs) have been observed following a thermal quench during Experimental Advanced Superconducting Tokamak–intended disruptions, which are triggered by massive gas injection. Electrostatic fluctuations
