英文摘要A recent EAST experiment has successfully demonstrated long pulse steady-state high plasma performance scenario and core-edge integration since the last IAEA in 2018. A discharge with a duration over 60 s with beta (P) similar to 2.0, beta (N) similar to 1.6, H-98y2 similar to 1.3 and an internal transport barrier on the electron temperature channel is obtained with multi-RF power heating and current drive. A higher beta (N) (beta (N) similar to 1.8, beta (p) similar to 2.0, H-98y2 similar to 1.3, n (e)/n (GW) similar to 0.75) with a duration of 20 s is achieved by using the modulated neutral beam and multi-RF power, where several normalized parameters are close or even higher than the phase III 1 GW scenario of CFETR steady-state. High-Z impurity accumulation in the plasma core is well controlled in a low level by using the on-axis ECH. Modeling shows that the strong diffusion of TEM turbulence in the central region prevents tungsten impurity from accumulating. More recently, EAST has demonstrated compatible core-edge integration discharges in the high beta (p) scenario: high confinement H-98y2 > 1.2 with high beta (P) similar to 2.5/beta (N) similar to 2.0 and f (bs) similar to 50% is sustained with reduced divertor heat flux at high density n (e)/n (GW) similar to 0.7 and moderate q (95) similar to 6.7. By combining active impurity seeding through radiative divertor feedback control and strike point splitting induced by resonant perturbation coil, the peak heat flux is reduced by 20-30% on the ITER-like tungsten divertor, here a mixture of 50% neon and 50% D-2 is applied.
