Transitions of turbulence in plasma density limits
A series of BOUT [X. Q. Xu et al., Phys. Plasmas 7, 1951 (2000)] simulations is conducted to investigate the physical processes which limit the density in tokamak plasmas. Simulations of turbulence in...

Formation of electron internal transport barrier and achievement of high ion temperature in Large Helical Device
An internal transport barrier (ITB) was observed in the electron temperature profile in the Large Helical Device [O. Motojima et al., Phys. Plasmas 6, 1843 (1999)] with a centrally focused intense ele...

A previously published analytical formula for the error-field penetration threshold in rotating tokamak plasmas is successfully benchmarked against nonlinear magnetohydrodynamical simulations in slab geometry. Moreover, the fundamental assumption underlying the derivation of this formula, namely, that the response of a flowing plasma to a low amplitude, quasistatic, resonant magnetic perturbation is governed by linear, constant-
layer physics, is verified over a wide range of plasma parameters, which includes the parameter range relevant to Ohmic and neutral beam injection start-up discharges in modern-day tokamaks. It is concluded that the formula in question can be used to estimate error-field penetration thresholds in such plasmas. ©2003 American Institute of Physics.
