Abstract

We carry out transport simulations of the L-H transition by the Shaing L-H transition model based on ion orbit losses, and find that the time scale of the L-H transition and the time scale for development of the H-mode pedestal are consistent with experimental observations. We also compare the power threshold derived from the Shaing L-H transition model with L-H transition threshold power scaling laws. We find that the magnetic field, Bt, plasma density, ne, and plasma current, Ip, scaling can be reproduced.
