Abstract :
We report on a study of the neutralization process in the DIII-D neutral beam system. Measurements of the neutralization efficiency are compared to theoretically predicted values and the potential for neutralization efficiency deficit is explored. A molecular spectroscopic technique is used to measure the neutralizer gas temperature and the results are used in a Monte-Carlo mode to study the neutralizer gas dynamics.
