摘要：The characteristics of divertor plasmas are investigated dynamically using a one-dimension-in-space and three-dimension-in-velocity particle-in-cell Monte Carlo collision simulation technique, and it is found that a strong magnetic field with a large incident angle of the magnetic field on the divertor plate gives rise to a hybrid electrostatic wave, which is made of waves with distinctive frequencies. These waves are then identified as being related, respectively, to the lower hybrid wave mode and electron Bernstein wave modes. The wave associated with the lower hybrid wave mode dominates the potential fluctuation, modulates the incident energy flux onto the divertor plate in a large magnitude and causes the wave-like variation of impurity production from the carbon-based divertor plate.
