Abstract A series of steady-state H-mode discharges have been conducted on Experimental and Advanced Superconducting Tokamak (EAST) to demonstrate that, under a given discharge condition during operation sustained by lower hybrid wave current drive electron cyclotron heating. Results show that plasma confinement can bifurcate into distinct high-confinement modes based initial conditions. Theoretical analysis reveals the deposition power driven current, which together shape q-profile, depend...
Abstract The attainment of a reliable equilibrium is critical aspect tokamak experiments and physics analysis. A common method for establishing current involves reconstructing it from indirect measurements, such as those obtained polarimeter-interferometers (POINT) motional Stark effect (MSE) systems. However, uncertainties still exist in the reconstruction results. For on EAST tokamak, which based POINT system, primary sources uncertainty are limited scope measurements sensitivity process....
We are developing a multicharged ion beam transport program. The program is dedicated to numerical simulation of the behavior highly charged and optimization optics in lines realized on PC with Windows user interface Microsoft Visual Basic. Among all ions different charge states beam, exchange electrons between low or neutral atoms residual gas taken into account using classical molecular over-barrier model Monte Carlo method. Therefore, code able describe changing state distribution along...
Abstract In recent experiments on EAST with neutral beam injection (NBI) and radio frequency (RF) waves (lower hybrid wave (LHW) electron cyclotron waves) heating, it was observed that an increase in the line-averaged density a decrease plasma internal inductance occurred duration of NBI. To explain experimental observation, simulations are conducted by using equilibrium code EFIT transport codes ONETWO TGYRO. It is shown L-H transition triggered right after injected, leading to formation...
