                      the helium plasma exposed tungsten has been investigated on
                      the linear device PSI-2. A nanoscale undulating surface
                      structure having a periodic arrangement is formed for
                      temperatures below 1073 K, in contrast to the fuzz
                      nanostructure formation in a higher temperature range. The
                      crests of undulation align with the $\langle 1\,0\,0\rangle
                      $ direction. The interval of the undulation is narrowest at
                      the crystal grain of {1 1 0} surface. The interval
                      becomes wider as the crystal grain surface tilts away from
                      the {1 1 0} surface, and the undulating surface
                      structure is not formed near the {1 0 0} surface. The
                      height of undulations is $\sim 8$ nm, independently of the
                      interval of the undulations, and it corresponds to the depth
                      of the layer heavily damaged due to helium plasma exposure.},
