自早期托卡马克装置以来，等离子体壁相互作用一直被认为是一个重要的课题。反应堆计算和最近对比例定律的探索为这一课题注入了新的动力。现在，轻杂质和重杂质都得到了更好的控制。在过去的两年里，在目前的机器中，有效离子电荷已经减少到几乎1。并对不同实验室的实验结果进行了详细的比较。墙体的预清洁和吸尘以及降低边缘等离子体的温度被证明是有效的。并对今后的发展提出了看法。
Plasma wall interactions have been recognized as an important topic since early tokamak machines. Reactor calculations and the search for scaling laws recently gave a new impetus to this subject. Better control of both the light and heavy impurities is now obtained. In the last two years the effective ionic charge has been reduced to almost one in present machines. Details are given comparing the results from different laboratories. Pre-cleaning and gettering of the walls as well as lowering the temperature of the edge plasma have proved to be efficient. Comments are made on future developments.
