ASDEX升级计划用钨涂层石墨瓦覆盖主燃烧室内壁的隔热层。四个瓦片安装在不同的极向位置的热屏蔽和删除后，一个完整的实验活动。在插入之前通过卢瑟福背散射（RBS）分析以及在移除之后通过RBS和颗粒诱导的X射线发射来分析瓦片。这是一个调查的极向和环面侵蚀的瓷砖由于溅射电荷交换中性和离子的影响。
There are plans at ASDEX Upgrade to cover the heat shield of the inner main chamber wall with tungsten coated graphite tiles. Four tiles were installed at different poloidal positions of the heat shield and removed after a full experimental campaign. The tiles were analysed by means of Rutherford backscattering (RBS) analysis before insertion and by both RBS and particle induced X ray emission after removal. This is an investigation of the poloidal and toroidal erosion profiles on the tiles due to sputtering by charge exchange neutral and ion impact.
