1. Integrated Operation of Steady-state Long Pulse H-mode in EAST
A world record discharge of s H-mode achieved with W-divertor
VLoop~ 0.0, H98y2 ~1.1, Ptot ~3.5 MW
Steady-state fully non-inductive high-bP scenarios up to 25 s demonstrated with extension of operational regime up to βP~2.0 and βN~1.6 using LHCD and ECH
High CD efficiency at high density with low recycling wall and integrated control
High fBS~40-50% with high density fGr~ and H98y2>1.0 at q95~
Broad q-profile, Shafranov shift ( βP) and e-ITB is key to high performance
Small/no ELM is essential for Steady-state Operation
Zero or low torque experiments (low toroidal rotation) on EAST may contribute to ITER
VLoop ~ 0
q95 ~ by only RF H&CD
on W-Divertor
