Abstract

A new concept of multijunction-type antenna has been developed, the Passive Active Multijunction, which improves the cooling of the waveguides and the damping of the neutron energy (for ITER) compared to Full Active Multijunction. Due to the complexity of the structures, prototypes of the mode converters and of the Passive-Active-Multijunction launcher were fabricated and tested, in order to validate the different manufacturing processes and the manufacturer's capability to face this challenging project. This paper describes the manufacturing process, the tests of the various prototypes and the construction of the final Passive-Active-Multijunction launcher, which entered into operation in October 2009. It has been commissioned and is fully operational on the Tore-Supra tokamak, since design objectives were reached in March 2010: 2.75 MW - 78 s, power density of 25MW/m2 in active waveguides, steady-state apparent surface temperatures < 350 °C; 10 cm long distance coupling.

Iter类低混合无源有源多结天线的制造与测试

提出了一种新的多结型天线概念，即无源多结天线，与全有源多结天线相比，它改善了波导的冷却和中子能量的阻尼(用于ITER)。由于结构的复杂性，制造和测试了模式转换器和被动-主动多结发射器的原型，以验证不同的制造工艺和制造商面对这一具有挑战性的项目的能力。本文描述了制造过程，各种原型的测试和最终的无源-有源多结发射装置的建造，该发射装置于2009年10月投入使用。自2010年3月达到设计目标以来，它已经在Tore-Supra托卡马克上投入使用并全面运行:2.75 MW - 78 s，有源波导功率密度为25MW/m2，稳态表观表面温度<350°C;10cm长距离联轴器。
