Abstract

Electron neoclassical transport is calculated taking non-local electron radial drift into account by using FORTEC-3D code which is based on δ f Monte Carlo method with time evolution of radial electric field, Er. This simulation is implemented as the first global analysis for high-electron-temperature discharges in LHD. The simulation result of Er is compared with the experimental observation and previous calculation results.
