“…A natural extension of beamlines and storage rings to higher densities are devices with plasma confinement with the main application being a nuclear fusion reactor. Temperatures up to 160 MK (≈ 10 keV) have been reached and sustained for O (1000) seconds at the EAST reactor [126] with ITER not too far behind [127]. The typical number densities required for fusion are in the range of 10 20 m −3 with plasma volume near 840 m 3 [128].…”

“…The ME-SXR diagnostic is also a useful tool to study ELMs and their effects on plasma macroscopic properties. In the 2015 RMP [30,31] experiment, ELM mitigation or suppression has been successfully achieved by RMP in EAST [32]. One typical discharge demonstrating the nonlinear transition from ELM mitigation to ELM suppression using an RMP current scan with a 45°phase difference [32] is shown in figure 7(a).…”

A new edge tangential multi-energy soft x-ray (ME-SXR) diagnostic with high temporal ( 0.1 ms) and spatial (∼1 cm) resolution has been developed for a variety of physics topics studies in the EAST tokamak plasma. The fast edge electron temperature profile (approximately from r a 0.6 to the scrape-off layer) is investigated using ME-SXR diagnostic system. The data process was performed by the ideal 'multi-foil' technique, with no priori assumptions of plasma profiles. Reconstructed ME-SXR emissivity profiles for a variety of EAST experimental scenarios are presented here for the first time. The applications of the ME-SXR for study of the effects of resonant magnetic perturbation on edge localized modes and the first time neon radiating divertor experiment in EAST are also presented in this work. It has been found that neon impurity can suppress the 2/1 tearing mode and trigger a 3/1 MHD mode.

“…As mentioned, ITER ( 19 ) and CFETR are designed for steady-state operation with a duration of over 1000 s. Previously, discharges lasting over 6 min have been achieved in Tore Supra ( 20 ), HT-7 ( 21 ), and EAST ( 22 ). In 2021, EAST reached a milestone, achieving steady-state plasma with improved energy confinement that could be operated for a duration exceeding 1000 s and with injected/extracted energy of 2 GJ.…”

Mastering nuclear fusion, which is an abundant, safe, and environmentally competitive energy, is a great challenge for humanity. Tokamak represents one of the most promising paths toward controlled fusion. Obtaining a high-performance, steady-state, and long-pulse plasma regime remains a critical issue. Recently, a big breakthrough in steady-state operation was made on the Experimental Advanced Superconducting Tokamak (EAST). A steady-state plasma with a world-record pulse length of 1056 s was obtained, where the density and the divertor peak heat flux were well controlled, with no core impurity accumulation, and a new high-confinement and self-organizing regime (Super I-mode = I-mode + e-ITB) was discovered and demonstrated. These achievements contribute to the integration of fusion plasma technology and physics, which is essential to operate next-step devices.
