主　　题：EAST tokamak high T_(e) integrated operation scenario 

摘      要：In 2021,EAST realized a steady-state long pulse with a duration over 100 s and a core electron temperature over 10 *** is an integrated operation that resolves several key issues,including active control of wall conditioning,long-lasting fully noninductive current and divertor heat/particle *** fully noninductive current is driven by pure radio frequency(RF)waves with a lower hybrid current drive power of 2.5 MW and electron cyclotron resonance heating of 1.4 *** is an excellent experimental platform on the timescale of hundreds of seconds for studying multiscale instabilities,electron-dominant transport and particle recycling(plasma-wall interactions)under weak collisionality.
