Abstract Since the 2012 International Atomic Energy Agency Fusion Energy Conference
(IAEA-FEC), significant advances in both physics and technology has been made on the …

In magnetic confinement fusion devices, supersonic molecular beam injection (SMBI) is
commonly used as a fueling method, which has also performed well in physical studies …

A total power injection up to 0.3 GJ has been achieved in EAST long pulse H-mode
operation of 101.2 s with an ITER-like water-cooled tungsten (W) mono-block divertor, which …

The mission of HL-2A is to explore the key physical topics relevant to ITER and to the
advanced tokamak operation (eg the operation of future HL-2M), such as the access of H …

In the Quiescent H-mode (QH-mode) regime, the edge harmonic oscillation (EHO), thought
to be a saturated kink-peeling mode (KPM) driven unstable by current and rotation, is found …

Improved energy confinement mode (I-mode) has been observed on the HL-2A tokamak.
The I-mode features an edge transport barrier (ETB) in electron temperature and a low …

Impurity seeding experiments in ELMy H-mode plasmas by using supersonic molecular
beam injection (SMBI) have been performed in the HL-2A tokamak. Besides pure impurity …

Abstract Effect of the pedestal deposited impurity on the edge-localized mode (ELM)
behaviour has been observed and intensively investigated in the HL-2A tokamak. Impurities …

Large edge localized modes (ELMs) typically accompany good H-mode confinement in
fusion devices, but can present problems for plasma facing components because of high …

Active control of the excessively high heat and particle fluxes on the divertor target plates is
of fundamental importance to the steady state operation of tokamaks, especially for fusion …
