dc.description.abstract© 2021 National Research Center Kurchatov Institute. All rights reserved.A simple 3-dimensional model LNB (Light Neutral Beam) is proposed for fast ions current evaluation in fusion devices. The model implements analytical expressions for plasma description, fast ion generation and slowing down. LNB model allows one to evaluate the beam ionization in plasma volume, fast ions thermalization [1], current drive, and phase distributions. The technique can be compared with the analytical approach adopted in system codes, but LNB takes into account the particular details of beam-plasma shaping; thus all the beam-driven quantities in plasma are obtained regardless to the empirical scaling laws. The model is especially effective for compact and spherical devices optimization, as for those the injected beam box shape and the beam internal angular distribution can play an important role in the result power deposition and current drive. LNB provides a simple and efficient tool for fast verification, sensitivity analysis, and beam-plasma optimization. These are to be requisite in operation windows selection for fusion neutron sources (FNSs) design [2, 3].
