The Impact of Beam Deposition on Bootstrap Current of Fast Ion Produced by Neutral Beam Tangential Injection

【摘要】:The density profile of fast ions arising from a tangentially injected diffuse neutral beam in tokamak plasma is calculated.The effects of mean free paths and beam tangency radius on the density profile are discussed under typical HL-2A plasmas parameters.The results show that the profile of fast ions is strongly peaked at the center of the plasma when the mean free path at the maximum deuteron density is larger than the minor radius,while the peak value decreases when the mean free path at the maximum deuteron density is larger than twice that of the minor radius due to the beam transmission loss.Moreover,the bootstrap current of fast ions for various mean free paths at the maximum deuteron density is calculated and its density is proved to be closely related to the deposition of the neutral beam.With the electron return current considered,the net current density obviously decreases.Meanwhile,the peak central fast ion density increases when the beam tangency radius approaches the major radius,and the net bootstrap current increases rapidly with the increasing beam tangency radius.
