The Material and Plasma Evaluation System (MAPES) in the EAST tokamak has been built up and used to address a variety of plasma-material interaction (PMI) issues relevant to ITER in 2012 EAST campaign. The topics studied cover erosion/redeposition of plasma-facing materials and components, hydrogenic retention in the gaps of castellation structure, deterioration of diagnostic mirrors from impurity deposition and protective technique. An introduction of MAPES system and an overview of the recent experimental results are presented.
