Transient Electron Thermal Transport Analysis Accounting Oblique Electron Cyclotron Resonance Heating Injection To Magnetic Field Line

In response to recent upgrade of the raytracing code for the electron cyclotron resonance heating (ECH) in LHD, transient electron thermal transport is reanalyzed. The upgraded code LHDGauss-U takes into account the oblique injection of the ECH ray to magnetic field line. The obtained results show reduced transport hysteresis widths by up to similar to 20% where the heating absorption is less significant, but qualitative features of the transport hysteresis reported in previous studies are found to be preserved.
