The results of a 3-D (in constants of motion space) Fokker-Planck simulation of the collisional losses of fusion products in axisymmetric DT and DD discharges in TFTR are presented. The distributions of escaped ions over poloidal angle and pitch angle, and their energy spectra, are obtained. Axisymmetric collisional losses of fusion products are found to be less than 2 to 5%. The distribution of confined fusion products is shown to be strongly anisotropic and non-uniform in the radial co-ordinate, mainly for slowed-down fusion products with small longitudinal energy. A comparison between these modelling results and experimental data is made

TFTRにおける軸対称DTおよびDD放電中の核融合生成物の衝突損失に関する3次元(運動量空間における定数)フォッカー・プランクシミュレーションの結果を示す。ポロイダル角およびピッチ角に対する損失粒子の分布と、そのエネルギー・スペクトルを得た。軸対称衝突損失は2〜5%未満であることが見出された。閉じ込められた核融合生成物の分布は、特に減速された小さな縦方向エネルギーの粒子において、強い非一様性と動径方向の非対称性を示すことが明らかになった。これらのモデリング結果と実験データとの比較を行う。
