在Tore Supra的新CIEL结构中，所有面向等离子体的组件都被主动冷却。覆盖着碳的墙的表面积约为15平方米(其中2至4平方米与等离子体密切相互作用)。在这种配置下，稳态等离子体条件一直保持到4分钟25 S。在这些实验中，在整个排放过程中，保持规定密度所需的气体注入保持不变。排气流量也是恒定的，相当于注入流量的40×50%。因此，50×60%的注入粒子仍然被困在血管中，总保留率与等离子体持续时间成正比。由于在两次发射之间或通过氦辉光放电回收的气体量并不总是平衡注入的气体，因此可以得出结论，一定数量的氘仍然无限期地被困在容器中，看起来就像一个无限的储气库。这个储集层被认为是由共沉积层主导的，正如在容器的几个地方观察到的那样。最厚的沉积物(高达800微米)位于泵限制器的中和器前沿。它们呈柱状(典型的生长速率约为20 nm/S)，具有石墨状结构。它们的氚浓度为D/C~1%。相反，在被直接等离子体通量遮挡的区域，沉积层显示出更光滑的形状，其氘含量通常为~10？15%。
In the new CIEL configuration of Tore Supra, all the plasma facing components are actively cooled. The surface area of the wall that is covered with carbon measures about 15 m2 (2 to 4 m2 of which in close interaction with the plasma). Steady-state plasma conditions up to 4 min 25 s have been maintained in this configuration. In these experiments, the required gas injection to maintain the prescribed density remains constant during the whole discharge. The exhausted flux is also constant and equal to 40 ÷ 50% of the injected flux. Therefore, 50 ÷ 60% of the injected particles remain trapped in the vessel, the total retention being proportional to the plasma duration. Since the amount of gas recovered between shots or by He-glow discharges does not always balance the injected gas, it follows that a quantity of deuterium remains indefinitely trapped in the vessel, which appears as an infinite reservoir. This reservoir is believed to be dominated by co-deposited layers, as observed in several places of the vessel. The thickest deposits (up to 800 µm) are observed on the leading edge of the neutralizers of the pump limiter. They display a column-like shape (typical growth rate ~20 nm/s) and have a graphite-like structure. Their deuterium concentration is D/C ~ 1%. Conversely, in regions that are shadowed from the direct plasma flux, the deposits show a smoother shape and their deuterium content is typically ~10 ÷ 15%.
