Taming harmful bursts and heat flux in high-confinement tokamak plasmas [PDF]
Nature CommunicationsA major challenge in tokamak fusion research is first-wall erosion caused by steady heat loads and sudden energy bursts known as edge-localized modes. Divertor detachment reduces steady-state heat flux, while resonant magnetic perturbations can suppress ...

Plasma heating and improvement of lower hybrid current drive efficiency by electron cyclotron waves on EAST [PDF]
EPJ Web of Conferences, 2023 The electron cyclotron (EC) system on EAST consists of four gyrotrons with a frequency of 140 GHz (second harmonic of the extraordinary mode), each of which is expected to deliver a maximum power of 1.0 MW and be operated at 100-1000 s pulse length ...

Sparse regression for plasma physics
Physics of Plasmas, 2023 Many scientific problems can be formulated as sparse regression, i.e., regression onto a set of parameters when there is a desire or expectation that some of the parameters are exactly zero or do not substantially contribute.

Investigation of the Water Draining Process Pushed by Gas for U-Type and Z-Type Manifolds
Science and Technology of Nuclear Installations, 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
