摘要：A laser induced breakdown spectroscopy (LISS) system has been developed to measure and monitor the composition evolution on plasma facing materials (PFMs) of Experimental Advanced Superconducting Tokamak (EAST). As a necessity and important proof of principle experiment, LIBS analysis has been performed for lithium-deuterium co-deposition layer diagnosis of EAST divertor tiles in lab experiments. The distribution of deuterium retention has been obtained from the depth of 0.5-4 mu m in the divertor tiles. The deuterium/hydrogen concentration ratio was estimated as 0.17 +/- 0.02 in lithium-deuterium co-deposition layer. Moreover, the depth profile behaviors of lithium and deuterium indicate that the deuterium retention in divertor tile came from lithium-deuterium co-deposition processes during deuterium discharge in EAST. This work would improve the understanding of deuterium retention and lithium-deuterium co-deposition mechanism and give a guidance to optimize the LIBS system which will be a unique and useful diagnostic approach in EAST 2014-campaign.
