 note = {"In neutral beam heated plasma of CHS, which is a low aspect-ratio heliotron/torsatron device, the effect of rotational transform (chi) profile shape on plasma confinement and stability is studied by inducing a net plasma current (Ip).  In the case that the external chi is increased by Ip, very rapid H-mode transition (within ~0.2 ms) is observed at the thresholds of Ip and heating power, having all characteristics found in the tokamak H-mode.  There is no obvious difference in the H-mode characteristics between deuterium and hydrogen plasmas.  In the opposite case that the external chi is decreased by reversing Ip, the H-mode transition is not observed."},
