电子束离子阱非常适合实验室天体物理学，因为它们可以在碰撞激发的等离子体中产生几乎任何元素的任何电荷状态，这些等离子体的密度和温度与许多天文源相当。Lawrence Livermore EBIT设施已针对实验室天体物理学进行了优化，配备了一套专用仪器，并在该领域取得了重大进展。本文回顾了LLNL在编制综合谱表、发现极紫外和软X射线区域的磁力线诊断以及EBIT和NSTX托卡马克的密度诊断方面所做的一些工作。PACS编号：95.30.Ky，32.30.Rj，95.75.-z，95.85.Nv，97.10.Ex，95.55.Ka，95.85.Mt，52.55.Fa
Electron beam ion traps are uniquely well suited for laboratory astrophysics because they can produce nearly any charge state of any element in a collisionally excited plasma that is comparable in density and temperature to many astronomical sources. The Lawrence Livermore EBIT facility has been optimized for laboratory astrophysics with a suite of dedicated instruments and has made significant advances in this field. This paper reviews some of the work performed at LLNL in compiling comprehensive spectral catalogues, discovery of a magnetic field line diagnostic in the EUV and soft X-ray regimes, and density diagnostics on EBIT and at the NSTX tokamak.PACS Nos.: 95.30.Ky, 32.30.Rj, 95.75.–z, 95.85.Nv, 97.10.Ex, 95.55.Ka, 95.85.Mt, 52.55.Fa
