      abstract     = {Rare isotope tracer injection represents an established way
                      for following particle transport in fusion research, but a
                      tracer experiment is only as good as the tracer can be
                      followed and separated from the common isotope. Physical
                      models for transport analysis such as ERO2.0 require
                      accurate total amounts of deposition with high spatial
                      resolution. This work describes an extended high throughput
                      NRA post analysis approach together with the surface
                      analysis results of 2 technically rough graphite-tiles of
                      150x150 mm2 surface area exposed to D and He plasmas in
                      EAST.The applied 1.43 MeV deuteron beam NRA offers percent
                      range accuracy for layer thicknesses ranging from few 10 nm
                      to 20 µm. Optimisation of the beam line and beam optics
                      enables operation with ≤20 nA without reaching critical
                      radiation levels, resulting in a measurement time of 5-10 s
                      per spot. This enabled acquiring in total 3070 NRA points on
                      the central 46×46 mm2 cut-outs of each sample and an
                      adjacent part of equal size within 12 h of analysis time.The
                      layers contained $50-60\%$ D, $∼2\%$ 12C, and $∼3\%$ O.
                      The central 20 mm radius around the injection hole contains
                      $98\%$ of the total 13C deposition. NRA finds up to
                      5.8±0.9×1022 13C/m2 close to the hole with an e-folding
                      fall-off length of about 3-10 mm in every radial direction.
                      In the D discharge $24±2\%$ and $16±2\%$ in He of the
                      injected 13C are found on the tiles with triangle shaped
                      deposition profiles following ExB. The comparison to colour
                      fringe analysis and SIMS reveals the particular strength of
                      D-NRA regarding roughness, thick layers, and the separation
                      of 12C and 13C deposits, but in compatible regions all
                      methods agree. Compared to these, the NRA yields additional
                      information indicating depositing species and physical
                      processes.},
