Behaviour of Fast Ions During Fast Neutrals Injection in TFR 600

摘要

In TFR 600, the fast neutrals injection is done almost perpendicular to the magnetic field (75 exp 0 ) and it is very crucial to know experimentally the behaviour of the fast ions captured in the plasma. Furthermore, it is expected theoretically that perpendicular injection could be more susceptible to drive microinstabilities. So knowledge of fast ions behaviour is very important for example to do a good energy balance of the heated plasma. In this paper we present at first the electrostatic analyser which has been used to measure the fast ions lost by charge-exchange, secondly the modified Mont-Carlo code which predicts the classical energy spectrum and at last comparisons between the two results.
