Book Description

Passive charge exchange measurements were made for a variety of tokamak discharge conditions. The central ion temperatures were determined, corrected for profile effects, and investigated for classical scaling behavior. The ion temperatures measured from the charge exchange spectrum were compared to those measured by impurity doppler broadening and to later charge exchange measurements obtained via diagnostic neutral beam injection. A mixed gas experiment using both hydrogen and deuterium was performed to determine the feasibility of resolving both ion species in the plasma center using the charge exchange diagnostic
