SOLPS simulation of a dedicated ASDEX Upgrade Ohmic shot for scrape-off layer and divertor modelling is described. The tendency of the code to predict a colder and denser divertor plasma compared with the experiment for solutions that satisfy main boundary conditions (on the input power across the core/edge boundary, particle throughput and radiated power) and match upstream profiles is confirmed. Issues related to the role of neutral sources and sinks are discussed. In the interpretative modelling based on experimental upstream profiles, neither the neutral pressure in the divertor nor the method of fuelling was found to strongly influence the parameters at the outer target, which are primarily determined by the input power and separatrix density.

SOLPSシミュレーションによる、スクレイプオフ層およびダイバータモデリングのための専用ASDEX Upgradeオーミック放電の記述を行う。主境界条件(コア/エッジ境界を横切る入力パワー、粒子スループット、および放射パワー)を満たし、上流プロファイルに一致する解について、コードが実験と比較してより低温かつ高密度のダイバータプラズマを予測する傾向が確認された。中性粒子源およびシンクの役割に関連する問題について議論する。実験的な上流プロファイルに基づく解釈的モデリングでは、ダイバータ内の中性粒子圧力もフューエリング方法も、外側ターゲットにおけるパラメータに強く影響しないことが見出された。これらのパラメータは、主として入力パワーとセパラトリックス密度によって決定される。
