Abstract
In the GAMMA 10 tandem mirror, impurity ion radiation profiles were measured in two types of discharge and these discharges had different electron density regions. Applying the collisional radiative model, we evaluated the impurity density profiles. Then impurity penetration from plasma edge into the core was estimated by considering the particle balance equation. It is shown that each discharge mode has a different decay length of impurity atom.gn
