The main topics for EAST campaign 2021 include:

1.Investigation of transport and confinement with dominant electron heating and low momentum input among different RF heating schemes and/or mixture with NBI, aiming improved confinement and higher bootstrap current fraction,

2.Development of steady-state scenarios for long pulse high performance plasma operation (H98>1.2 for >100s) with tungsten divertors,

The physics basis highly related with development of high performance steady-state scenarios is appreciated, including plasma control, scenarios for efficient heating and current drive, divertor heat/particle exhaust, instability mitigation, impurity transport and global particle balance control in long time scale, physics and technologies in supporting of ITER and CFETR operation scenario development.
