Spatially resolved measurements of fully ionized low-Z impurities in the PDX tokamak

  • 1. Plasma Physics Laboratory, Princeton University, Princeton, New Jersey 08544

Description

Fully ionized oxygen and carbon in PDX plasmas are detected via charge-exchange recombination reactions between the impurities and hydrogen atoms from a low-power neutral beam. The C6+ and O8+ ions are observed out to radii beyond the limiter, which is in contrast to expectations based on coronal equilibrium but consistent with a simple diffusive transport model. Central values of Z/sub eff/ obtained with these measurements agree with values obtained from plasma resistivity and visible bremsstrahlung measurements
