质谱仪在激光等离子体物理研究中的应用

MASS SPECTROMETRY AND ITS APPLICATIONS IN LASER PLASMA STUDIES

在对激光等离子体相互作用的研究中 ,物质由于在激光场的作用下离化而形成各种离化态的离子 ,研究这些离子的特性可以深入理解激光与等离子体相互作用过程 .质谱仪能提供离子的最高离化态、平均电荷态、能量分布和丰度等重要信息 .文章介绍了质谱仪的原理及其在激光等离子体中的应用 .

The ion diagnostics in high temperature plasmas produced by the interaction of intense laser radiation with targets provides critical information on the average and maximum charge state of ions, ion energy distributions, and the abundance of ion species in laser plasmas. Mass spectrometry is therefore very important. Its principle is presented, and various types of mass spectrometers together with their applications in laser plasmas are described.
