      abstract     = {Surface morphology development and sputtering behavior of
                      Cr, as a test material, have been explored under He plasma
                      exposure at a low incident ion energy of ∼80 eV in
                      multiple linear plasma devices: PISCES-A, PSI-2, and
                      NAGDIS-II. From comparison of the experiments in these
                      devices, deposition of a small amount of heavier impurities
                      (Mo in NAGDIS-II and Ta in PISCES-A) onto Cr is found to
                      result in the formation of cone structures on the Cr surface
                      due to preferential sputtering, resulting in a significant
                      reduction (up to ∼10 times) in the sputtering yield of Cr
                      due to line-of-sight redeposition onto the neighboring
                      cones. The heavier impurities are thought to originate from
                      a sample holding cap/cover, which can be sputtered by a
                      trace amount of intrinsic impurities (C, O, etc) as well as
                      by Cr ionized in the plasma. It can be concluded from the Cr
                      experiments, as well as additional Be data collected in
                      PISCES-B, that heavier impurity deposition plays a major
                      role in the cone structure formation, while other mechanisms
                      (e.g. surface irregularity and oxide) also exist.},
