1. 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

2. 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?
