Abstract

The JET (Joint European Torus) pumped divertor aims at demonstrating an effective method of impurity control with quasi-stationary plasmas of thermonuclear grade in a next step relevant, axisymmetric configuration. The magnetic configuration is produced by a set of four coils internal to the JET vacuum vessel. These coils can produce a range of configurations and also sweep the magnetic field lines along the target plates. The target plates will initially use radiation-cooled beryllium tiles, but actively cooled target plates able to operate in steady state at up to 40 MW are planned in a second phase. The design also features a cryopump which will remove a fraction of the particles recycled in the vicinity of the target plates. The configuration of the ICRH (ion cyclotron resonance heating) antennae and wall protections has been modified to match the new plasma shape. All components have been designed to resist the large forces generated by halo currents.<>

JET泵送分流器的设计

JET(联合欧洲环面)泵送分流器旨在展示一种有效的方法，在下一步相关的轴对称配置中使用热核级准静止等离子体控制杂质。磁性结构是由JET真空容器内部的一组四个线圈产生的。这些线圈可以产生一系列的配置，也可以沿着目标板扫磁场线。目标板最初将使用辐射冷却的铍瓦，但计划在第二阶段使用能够在高达40兆瓦的稳定状态下运行的主动冷却目标板。该设计还具有一个低温泵，它将去除目标板附近回收的一小部分颗粒。ICRH(离子回旋共振加热)天线和壁保护的配置已被修改以匹配新的等离子体形状。所有的部件都被设计成能够抵抗由光晕电流产生的巨大力量
