Abstract: Nanostructure formation on molybdenum surface due to helium plasma exposure is investigated, focusing on the temperature band for fiber-form nanostructure growth. A precise temperature measurement can be obtained using thin thermocouples inserted into sheet specimens. The temperature range for nanostructure growth is determined to be 800 ~ 1050 K under the incident helium ion energy of 50 ~ 100 eV. The surface morphologies at around upper and lower boundary temperatures are different from a standard fiber-form nanostructure. The nano-fibers of molybdenum in a standard case was found to have a diameter of about 50 nm, while that of tungsten is a half of the molybdenum fibers.
