abstract = {Long pulse discharges in the Large Helical Device have
often been interrupted by large amounts of dust particle
emission from the divertor region caused by the exfoliation
of carbon-rich mixed material deposition layers. The plasma
wall interaction code ERO2.0 has provided the simulation
results of the three-dimensional distribution of the carbon
flux density in the divertor region which is quite
reasonable with the observed distribution of the carbon-rich
deposition layers. The code has also succeeded in
reproducing the reduction of the carbon deposition layers on
dome plates by changing the target plate configuration in
the divertor region. The ERO2.0 simulations have also
successfully explained dust particle emission from the
inboard side near the equatorial plane for the new target
plate configuration at the termination of a long pulse
discharge. These simulation results prove that the ERO2.0
code is applicable to predicting the possible position from
where the dust particles are released, and to designing an
optimized divertor configuration for performing stable long
pulse discharges with controlled dust particle emission.},
