THE EFFECT OF NEUTRAL BEAM DEPOSITION ON HEATING AND CONFINEMENT IN ASDEX
The effect of the beam deposition profile on heating and confinement in ASDEX has been studied by comparing plasmas with center-peaked and hollow beam deposition profiles. There is no significant difference in global energy confinement time and central electron energy density. A hollow deposition profile reduces the central electron energy density. A hollow deposition profile reduces the central electron heat transport at least by a factor of two. A beam energy of 75 keV/nucleon would be sufficient in order to generate the same (a/lambda=const.) deposition profile for a full density, full bore scenario in NET.
