Relation of neutral beam injection to impurity behavior and extension of plasma parameters on ORMAK

OSTI ID:7290067
Neutral beam injection extends the plasma parameter range (n/sub e/, ..beta../sub T/, q, T/sub i/) in ORMAK over that obtainable with ohmic heating alone. Impurity radiation also increases due to the added power, especially with counterinjection. Impurity trapping of injected beam neutrals is observed, but the large toroidal rotation velocities expected for unidirectional injection do not occur.
