Monte Carlo simulation of neutral beam injectioninto a field reversed configuration

A Monte Carlo code is employed to study the interaction of neutral beams with a field reversed configuration (FRC). The code follows the exact particle trajectories in the self-consistent equilibrium calculated including the beam and plasma currents. For high enough beam currents, a self-consistent confining effect is observed which prevents expansion of the beam along the FRC axis. The beam current drive and the power and momentum transferred are calculated for a variety of beam parameters. The results are slightly affected by the details of the injection geometry. The dependence on the neutral current IN and beam energy EN is influenced by several factors, such as particle losses through the ends, the density increase around the injection region and the finite Larmor radius effect.

モンテカルロコードを用いて、中性ビームと磁場反転配位(FRC)との相互作用を研究する。このコードは、ビーム電流とプラズマ電流を含めて計算された自己無撞着平衡状態における正確な粒子軌道を追跡する。十分に高いビーム電流に対しては、FRC軸に沿ったビームの膨張を防ぐ自己無撞着な閉じ込め効果が観測される。ビーム電流駆動、ならびに輸送される電力と運動量は、さまざまなビームパラメータについて計算される。結果は、入射形状の詳細によってわずかに影響を受ける。中性電流INおよびビームエネルギーENへの依存性は、端部を通じた粒子損失、入射領域周辺の密度増加、有限ラーマー半径効果など、いくつかの要因によって影響を受ける。
