Data set for "Density compensation and stored energy recovery in resonant magnetic perturbation suppressed edge-localized mode H-mode plasmas using pellet fueling on EAST"

The fueling of plasmas using frozen pellets in steady-state quiescent H-mode plasmas with edge-localized modes (ELMs) suppressed by external magnetic perturbations (RMPs) wassuccessfully demonstrated on the EAST tokamak in plasmas with similar shapes to those in ITER with q95 ~ 3.8, and triangularity δ ~ 0.45. During the fully suppressed-ELM phaseusing RMPs, the plasmas were refueled by deuterium pellets with a frequency of 5 Hz from ~40 cm above the mid-plane on the low field side. The results show that the pellet fueling would partially compensate density, which decreased due to the effect of pump-out induced by RMPs. It was interesting to discover that the stored energy of the plasma could be raisedto the value from before RMP application using pellet injection, which is rarely reported in other tokamaks. As for ELMs, they reappeared with a size smaller than the ELMs before RMPapplication accompanied with a magnetic coherent mode termination, however, the ELMs were still mitigated to a certain extent. Meanwhile, a similar experiment using supersonicmolecular beam injection fueling was also carried out, which confirmed that pellet fueling is better for raising plasma stored energy. The data set contains the main data supporting the above points.
