Abstract
A new experimental technique to investigate the particle confinement of energetic ions during their slowing-down process is developed for charge exchange neutral particle diagnostics. The method is based on the maximum entropy and the maximum likelihood method and is used for the neutral beam short pulse experiment. The method assumes that the energy loss of the fast ions is given by the classical deceleration rate at their birth orbit. It will not require the bulk neutral distributions and the energetic ion distribution in plasmas. The method provides the spatial distribution of confinement time of energetic particles on their orbit during the slowing-down processes. The method of the analysis is described and the application to the experimental data is shown in this article.
