      abstract     = {To evaluate the erosion effects of charge exchange (CX)
                      neutrals on first wall materials, aluminum (Al) coated
                      samples installed in a cylindrical sleeve were exposed to
                      EAST plasmas with the Material and Plasma Evaluation System
                      (MAPES). The 3D-GAPS code was firstly used to simulate the
                      dedicated experiments with the neutral energy spectrums
                      measured by the Low Energy Neutral Particle Analyzer located
                      at the MAPES. The modeled Al erosion rates with isotropic
                      angular distributions for incident D neutrals are consistent
                      with the measured erosion thicknesses of Al layer by
                      Rutherford backscattering spectrometry before and after the
                      plasma exposure. The effects of neutral reflection
                      coefficients and the heights of cylindrical sleeve on
                      material erosion are also studied. The measured material
                      erosion rate by CX neutrals in EAST verified by the modeling
                      can help to us understand the effects of neutrals on first
                      wall erosion, which is an important erosion process in
                      future fusion reactors.},
