中文摘要

聚变能研究的目标是创造一个“瓶中之星”。磁聚变研究已经发展到一个地步，现在的问题是“瓶子”。壁甲受到热等离子体的强烈侵蚀。一些被侵蚀的物质从等离子体中沉积回原来的位置，不会造成任何问题。然而，大部分物质在再次沉积之前会在等离子体内部迁移一段距离。后者产生了严重的问题：(i)装甲寿命损失，（ii）沉积物堆积，可能停止反应堆运行，（iii）由于共沉积捕获而损失氚燃料，（iv）产生具有安全（化学爆炸）影响的粉尘，等等。
英文摘要
The aim of fusion energy research is to create a 'star in a bottle'. Magnetic fusion research has advanced to the point where the 'bottle' is now the problem. The wall armour is strongly eroded by the hot plasma. Some eroded material deposits back out of the plasma at the original location, causing no problem. However, much of the material migrates some distance within the plasma before depositing out again. The latter creates serious problems: (i) loss of armour lifetime, (ii) pile-up of deposits which can stop reactor operation, (iii) loss of tritium fuel due to co-deposition trapping, (iv) dust creation with safety (chemical explosion) implications, etc.
