Plasma physics of intense neutral beam heating in tokamaks

The major conclusions of the workshop were: 1) neutral beam heating is still an infant and difficult technology: 2) neutral beam heating experiments have just begun to explore the P/sub inj/ much greater than P/sub ohmic/ regime; 3) no obvious injection-specific limits of neutral beam heating have been found for powers up to 2.4 MW in PLT, or up to greater than or equal to 1 MW in the smaller DITE, ISX-B and T-11 experiments; 4) an ever-increasing number of high power injection experiments are planned over the next few years; and 5) the classical, Coulomb-collision based theory of neutrlal beam injection is in good agreement with experimental results and is presently progressing to a stage which is primarily one of computer code development and experiment evaluation and interpretation
