Wall conditioning effects of boron powder injection in KSTAR with a tungsten divertor

Nuclear Fusion
Boron powder dropped into KSTAR plasmas decreased the radiated power, core electron density, and $Z_\mathrm {eff}$ , indicating that the ablated and redeposited boron powder helped to condition the plasma-facing surfaces.

Gyrokinetic simulations of the effects of magnetic islands on microturbulence in KSTAR

Nuclear Fusion
Gyrokinetic simulations are utilized to study effects of magnetic islands (MIs) on the ion temperature gradient (ITG) turbulence in the KSTAR tokamak with resonant magnetic perturbations. Simulations show that the transport is controlled by the nonlinear

Revised error field assessment in KSTAR with profile diagnostics of resonant field penetration

Nuclear Fusion
The assessment of the $n = 1$ intrinsic error field in KSTAR has been revised in three respects. First, a local penetration timing criterion is defined from electron cyclotron emission (ECE) and charge exchange spectroscopy (CES) signatures near the ...
