用于高电荷态离子与表面相互作用研究的原子物理实验平台

An experimental platform for the atomic physics research in the interaction of HCI-surface

在重离子加速器国家实验室ECR离子源上,成功组建了用于高电荷态离子与表面相互作用研究的原子物理实验平台;利用该实验平台,研究了用不同电荷态和不同速度的高电荷态离子与不同表面相互作用的可见光和X射线发射的情况,同时还研究了高电荷态Xe离子轰击晶体材料所引起的材料性质和表面结构变化的情况.

We have built a research platform for atomic physics on the electron cyclone resonance （ECR） ion resource of the national laboratory of the Heavy Ion Research Facility in Lanzhou （HIRFL）. On this platform, we have systematically investigated the visible light and X-rays in the interaction of highly charged ions （HCI） which had a wide range of charge state and impact velocities with a variety of solid surfaces, on the other hand, the change of the surface character and structure after impacting by HCI had also been studied.
