Abstract

Neutral beam injection has been recognized as one of the most effective means for plasma heating. The preliminary data of 50 keV, 100 s and 80 keV, 1 s beam extraction have been obtained on the EAST neutral beam injector (NBI) test-stand. In this paper, beam energy distribution deposited on each heat load component and neutral efficiency of EAST-NBI has been measured using water-flow calorimetry and beam divergence angle and perveance have been analyzed according to the data obtained from the thermocouples installed in the calorimeters.
