Abstract
Samples exposed at various minor radii in PLT to small numbers of high power discharges have been analyzed for the amount and depth distribution of implanted hydrogen isotopes and higher Z impurities. Comparisons of the measured H,D concentrations and depth profiles with laboratory implantations and calculated depth profiles give the energy and fluence of the hydrogen implanted in the PLT samples. For a Maxwellian distribution, characteristic temperatures of 500 to 600eV due to plasma charge exchange, and 50 to 350eV due to ions at the plasma edge are obtained. Also a 5-40keV component is observed due to neutral beam injection.
