Abstract

Resonance ionization spectroscopy has been applied to analyze tokamak collector probes. The edge plasma of the MT-1 tokamak was investigated using nonintrinsic sodium impurities injected by the laser blow-off technique. Silicon single crystal deposition probes were analyzed by laser atomization, followed by the resonance ionization method. The unique sensitivity of the selective photoionization made it possible to determine the radial distribution of impurities on a probe exposed to a single tokamak discharge.
