Abstract

Hydrogenlike oxygen and carbon lines from transitions (Δn=1) between levels of high principal quantum number n, with wavelengths above 2000 Å have been observed. Observations of such transitions were possible due to charge-exchange processes during neutral beam injection of hydrogen atoms into the Princeton Large Torus tokamak. The lines are O VIII 2976 Å (8-7 transitions), C VI 3434 Å (7-6), and C VI 5291 Å (8-7). Application of these lines for ion temperature measurements and initial observations of neutral beam vertical distributions in the plasma are presented.
