Control of huge heat and particle fluxes on the divertor plates is
a quite essential issue for success of ITER and DEMO reactor
One possible solution is usage of the plasma detachment, which is
normally unstable but effectively stabilized with resonant magnetic
perturbation (RMP) field in the Large Helical Device (LHD)
Experimental setup of a fast scanning Langmuir probe
We have firstly measured Isat distribution change
and intermittent fluctuation near the magnetic
island X-point in the LHD by using a fast
scanning Langmuir probe
Measured Isat distributions
and fluctuation
