Simulation of neutron emission spectra from neutral beam-heated plasmas in the EAST tokamak

The neutron emission spectrum from neutral beam-heated plasmas of the Experimental Advanced Superconducting Tokamak (EAST) is investigated based on first-principles simulations of the fast deuteron energy distribution. Parametrized plasma profiles are used to determine the beam deposition and fast deuteron distribution function using the NUBEAM code. The deuteron distribution is also interpreted with the help of empirical models and the components in the neutron energy spectrum are computed for different viewing lines using a Monte Carlo method. The resulting observational possibilities are discussed for the case of a time-of-flight neutron emission spectrometer optimized for EAST.

EAST(実験先進超伝導トカマク)の中性粒子ビーム加熱プラズマからの中性子放出スペクトルを、高速重陽子エネルギー分布の第一原理シミュレーションに基づいて調査した。パラメータ化されたプラズマ分布を用いて、NUBEAMコードによりビーム入射と高速重陽子分布関数を決定した。重陽子分布は経験モデルの助けも借りて解釈され、中性子エネルギー・スペクトルの成分はモンテカルロ法を用いて異なる視線に対して計算された。得られた観測の可能性は、EAST用に最適化された飛行時間型中性子放出分光計の場合について議論される。
