Laser blow-off experiments on ASDEX
Abstract
A laser blow-off system was installed on the ASDEX Tokamak and used in investigations of the impurity behavior under different plasma conditions. Results reveal considerable improvement of the impurity confinement time in OH plasmas near the density limit; influence of impurities on edge localized modes; strong dependence of the impurity confinement time on the gradient of the plasma current; and different impurity confinement under various heating conditions.
