Abstract
Possibility of controlling trapped electron instability in Tokamaks using a modulated neutral beam is investigated. Modulation of the beam is accomplished by a signal which is proportional to density fluctuations due to electron instability. Different modes of injection are investigated and oblique injection is found to be the best mode of injection. Particle input but not momentum input is found to be sufficient for the control purpose.Keywords
