即将到来的TCV偏滤器升级的中性粒子的分布和分离的发病的影响进行了研究，使用二维输运代码模拟。偏滤器升级的中心是安装一个气体挡板，以形成一个可变闭合的偏滤器室。SOLPS-ITER模拟预测，选择在2019年安装在TCV中的挡板几何形状将使偏滤器中性密度增加10.5倍，并且在典型的TCV单零欧姆加热场景（330 kW）中使中性压缩增加一个数量级。随着辅助加热系统（1.2MW）的增加，压缩进一步增加。模拟结果表明，偏滤器的体积功率损失增加，使访问更深的分离给定的上游密度和加热功率。各种TCV诊断，包括baratron，偏滤器光谱仪和可见光相机系统的观测预测，指导偏滤器挡板的效率的实验验证。
The effect of the upcoming TCV divertor upgrade on the distribution of neutrals and the onset of detachment is studied using 2D transport code simulations. The divertor upgrade is centered around the installation of a gas baffle to form a divertor chamber of variable closure. SOLPS-ITER simulations predict that the baffle geometry selected to be installed in TCV in 2019 increases the divertor neutral density by a factor ∼5 and the neutral compression by one order of magnitude in typical TCV single null, Ohmic heated scenarios (330 kW). The compression increases further with the addition of auxiliary heating systems (1.2 MW). Simulations show that volumetric power losses in the divertor increase giving access to deeper detachment for given upstream densities and heating power. Predictions for observations by various TCV diagnostics, including baratrons, divertor spectrometer and visible camera systems, are presented to guide the experimental verification of the efficiency of the divertor baffles.
