Presentation transcript:

Current-Hole Experiments have been performed on JET and JT-60 An experimental team was attempting to reverse the sign of the central current density in JET—could not make it go negative Jardin/Breslau J time R M3D simulations reproduced and explained experimental results as a form of magnetic reconnection that would occur when a surface with B=0 existed in tokamak t =17.5 t =0.0 t =22.5 t =34.0 t =28.125

Can we produce Current-Holes in CMOD? Edge LHCD and fast current ramp like in JET Can current hole be sustained for several skin times? Transport properties? Stability limits?
