托卡马克<s:1>配置变量（TCV）托卡马克正在进行升级，以进一步提高其研究常规和替代导流器配置的能力。为此，安装了模块化和可拆卸的气体挡板，以减少导流器和等离子体核心之间的耦合。挡板主要是为了抑制回收中性物向封闭通量表面的过渡。第一次使用气体挡板的实验表明，挡板分流器仍然适用于各种配置，包括雪花和super-X分流器。等离子体密度斜坡实验显示，与没有挡板的转向器相比，转向器中的中性压力增加了一个因子×5，从而定性地证实了用于指导挡板设计的SOLPS-ITER代码的模拟。与一系列新的和升级的转向器诊断一起，挡板TCV转向器现在用于验证ITER和下一步设备的转向器模型，特别强调几何变化。
The Tokamak à Configuration Variable (TCV) tokamak is in the midst of an upgrade to further its capability to investigate conventional and alternative divertor configurations. To that end, modular and removable gas baffles have been installed to decrease the coupling between the divertor and the plasma core. The baffles primarily seek to suppress the transit of recycling neutrals to closed flux surfaces. A first experimental campaign with the gas baffles has shown that the baffled divertor remains compatible with a wide range of configurations including snowflake and super-X divertors. Plasma density ramp experiments reveal an increase of the neutral pressure in the divertor by up to a factor ×5 compared to the unbaffled divertor and thereby qualitatively confirm simulations with the SOLPS-ITER code that were used to guide the baffle design. Together with a range of new and upgraded divertor diagnostics, the baffled TCV divertor is now used to validate divertor models for ITER and next step devices with particular emphasis on geometric variations.
