      abstract     = {The lifetime of the beryllium first wall in ITER will
                      depend on erosion and redeposition processes. The physical
                      sputtering yields for beryllium (both deuterium on beryllium
                      (Be) and Be on Be) are of crucial importance since they
                      drive the erosion process. Literature values of experimental
                      sputtering yields show an order of magnitude variation so
                      predictive modelling of ITER wall lifetimes has large
                      uncertainty. We have reviewed the old beryllium yield
                      experiments on JET and used current beryllium atomic data to
                      produce revised beryllium sputtering yields. These
                      experimental measurements have been compared with a simple
                      physical sputtering model based on TRIM.SP beryllium yield
                      data. Fair agreement is seen for beryllium yields from a
                      clean beryllium limiter. However the yield on a beryllium
                      divertor tile (with C/Be codeposits) shows poor agreement at
                      low electron temperatures indicating that the effect of the
                      higher sputtering threshold for beryllium carbide is
                      important. (C) 2011 EURATOM. Published by Elsevier B.V. All
