最近，在EAST上进行了面向等离子材料的常规锂涂层，使用了升级的蒸发炉和实时注入锂粉的两种方法。每天使用10-30g的锂涂层，H/(H+D)比已降至10%以下，杂质水平和MHD活性都得到了抑制。使用这些涂层技术，等离子体的性能得到了显著改善。例如，在2012年EAST战役开始时，就实现了10s的H模式等离子体。EAST已经开发了从真空室中去除锂涂层的技术，并记录了在通气口后等离子体性能的快速恢复。
Recently, routine coatings of plasma facing materials with lithium were carried out on EAST using both upgraded evaporative ovens and real-time injection of lithium powder. Employing daily lithium coatings of 10–30g, the H/(H+D) ratio has been decreased below 10% and both impurity levels and MHD activity have been suppressed. Using these coating technologies, plasma performance has been improved significantly. For example, a 10s H-mode plasma was achieved at the beginning of the 2012 EAST campaign. Techniques for removing Li coatings from the vacuum vessel have been developed in EAST and rapid recovery of plasma performance following air vents has been documented.
