自1992年以来，基于铜合金散热器结构和CFC装甲的可靠的高热通量PFC已经被开发出来。最终的结果是一个主动冷却的高热通量元件，它能够消除高达10 MW/spl middot/m/sup-2/静止运行条件。大约600个这些高性能的单独部件，然后制造和组装，以装备一个环形泵限制器（TPL）。该主要的容器内组件由平坦的环形连续盘（R/sub i/= 2.2 m，R/sub o/= 2.7 m）组成，覆盖7.6 m/sup 2/面积，并且由574个称为"指状物"的径向高热通量元件制成。在先前制造了200个专用于RF天线限制器的"短指元件"之后，在CIEL项目的框架内，于1997年开始制造装备TPL所需的主动冷却长指元件。虽然在系列制造过程中出现了一些问题，需要开发维修工艺，但最终交付已于2001年底成功实现。本文论述了沿着四年的第三方物流零部件制造过程中所获得的经验反馈。我们将展示遇到的问题，如何找到解决方案来实现组件的制造，并将强调需要学习的主要技术经验：验收标准，材料选择，工艺裕度。最后提出了一种替代优化设计的建议，迄今为止所取得的经验和进展的成果，主动冷却等离子体面向HHF组件的独特系列制造。这种反馈经验被认为是高度相关的，可用于ITER以及温德尔斯坦7-X。
Since 1992, reliable high heat flux PFCs based on copper alloy heat sink structures and a CFC armour, have been developed. The final result is an actively cooled high heat flux element that is capable of removing up to 10 MW/spl middot/m/sup -2/ stationary operating conditions. About 600 of these high performance individual components have then been manufactured and assembled in order to equip a toroidal pump limiter (TPL). This major in-vessel component consists of a flat toroidally continuous disk (R/sub i/=2.2 m, R/sub o/=2.7 m) covering a 7.6 m/sup 2/ area and made of 574 radial high heat flux elements called "fingers". Following a promising previous manufacture of 200 "short fingers elements" dedicated to RF antenna limiters, the fabrication of actively cooled long fingers elements required to equip the TPL was launched in 1997 in the framework of CIEL project. Although some issues appeared during series fabrication, requiring repair processes development, the final deliveries have been achieved successfully end 2001. The paper deals with the experience feedback that was gained all along the four years duration of the TPL components manufacture. We will show where issues were encountered, how solutions were found to achieve the fabrication of components and will highlight what are the main technical lessons to be learned: acceptance criteria, choice of materials, margins of processes. Finally a proposal of an alternative optimised design is presented, fruit of the experience gained and progress performed from this up to now, unique series manufacture of actively cooled plasma facing HHF components. Such feedback experience is considered highly relevant and available to ITER as well as to Wendelstein 7-X.
