摘要: Abstract The field-ion microscope has been used in a pilot investigation of the damage caused to tungsten surfaces following bombardment with low-energy helium ions. Such effects could be important because first wall fusion reactor will have withstand high doses these particles. observed total range 10 13 5 × 18 ions cm −2 found dose dependent. These results then related those derived from studies using more conventional techniques and this led conclusion that origin lies formation near-surface gas bubbles surface blisters.
