Abstract
A carbon probe in the form of a small filament has been used in the shadow of the limiter in the DITE Tokamak to trap the flux of energetic hydrogen atoms and ions. The trapped particles are released after a discharge by withdrawing the probe into a separate vacuum system and heating the filament. The gas released is measured mass spectrometrically to obtain quantitative information on the incident flux. Some preliminary measurements of flux to the wall and as a function of radial position of the probe are described.Keywords
