This campaign will be from February 27 to July 10 as follow:
1) February 27 - March 31,commissioning of EAST sub-systems: superconducting magnets,power supplies,plasma control,magnetic diagnostic calibration etc. commissioning of EAST machine: plasma setup (Ip=0.5MA，ne=2.0-4.0x1019/m3,BT=2.5T),mid-level heating and current drive power (5.0-6.0MW),self-consistency of plasma diagnostics;
2）April 1-30 (4 weeks),1000s H-mode and other major EAST targets of this campaign,investigating the following topics in long-pulse operation: plasma control,equilibrium & stability,transport & confinement,H&CD,particle and heat exhaust,core-edge integration, energetic particles.
3）May 1-July 10 ( 10 weeks),physical experiment for proposals, covering ongoing fundings/projects,open proposals on cutting-edge topics. Proposals should focus on the key issues of ITPA/CFETR.
* 2 weeks contingency included.
Plasma operation windows for this campaign:
Ip=0.3-0.7MA,BT<3.0T,3.0<q95<9.0,0.3<ne/nGW<0.8,USN/LSN/DN,4.0MW<Pheat<10MW.
Integrated high confinement and high beta scenario development toward ITER and CFETR,explore of high ion temperature operation with synergy effect of NBI,ICRF and ECRH,advanced plasma control methods developments for core-edge integration etc.
For high-power, long-pulse plasma confinement and transport, study the momentum and particle transport under steady-state operating conditions, focusing on high-Z impurity behavior under high-power heating, and explore internal transport barrier formation/sustainment at high ion temperatures. Study of the turbulence and transport characteristics under various operating conditions and the multi-scale interaction mechanism with multiple modes/scales (such as NTM, AE, EP).
MHD instabilities and 3D physics studies in low torque, low q95 plasmas in support of ITER high Q operation: ELM and divertor heat flux control by RMP,Core MHD and its interaction with 3D field,frontier studies in 3D physics etc.
Pedestal structure,stabilities and their impact on SOL transport,extension of small/no ELM regimes towards low q95 (q95~53) relevant to ITER high Q scenario;key physics in pedestal for high-performance high-density operation (especially with pellet injection),etc.
Detachment control compatible with core plasma,particle exhaust and recycling,material erosion and migration during long pulse operation.
EP velocity-space distribution with the synergistic effects of NBI and ICRF; the effect of non-axisymmetric magnetic fields on EP redistribution/loss with the impact on the first wall; the interaction of EP with other instabilities
