Laser-Induced Desorption of Impurities from the Macrotor Tokamak Walls
Flash heating by a laser pulse has been used to desorb loosely bound species from a
spot on the tokamak wall. Spectral analysis of the suddenly increased impurity radiation
from the plasma in front of the laser-heated spot gives information on the species and
the amount of impurity atoms present on the surface at a specific point in time of the
tokamak discharge, Loosely bound chromium has been found on the stainless-steel surface
