| Abstract: |
| The surface s character of the metallic first mirrors changes when the first mirrors made from polycrystalline W, SS, Mo located at different areas on the first wall of HT-7 were exposed to the plasma. was strdied After the experiment, the reflectivity of these mirrors and the component of their surface were analyzed in order to researching the change of their surfaces character. The results obtained show that the diffuse reflectivity of the mirrors made from three different materials has much change, at the same time, the specular reflectivity of mirrors made from W material has the least change. The results also show that the condition the mirrors located decides the change of the mirrors' surface. |
