Development of accelerator mass spectrometry using isotope-selective laser photodetachment

提出了同位素选择激光光剥离辅助紧凑加速器质谱（ISLP-AMS），包括开发高性能脉冲注入锁定Ti：蓝宝石激光器和使用激光烧蚀的脉冲负离子源。通过一个原型实验装置，证明了脉冲负碘离子的光剥离，并明确了其基本性能。这些结果表明，负碘离子源和注入锁定的Ti：蓝宝石激光器非常适合于用ISLP-AMS进行^I的痕量分析。

Compact accelerator mass spectrometry assisted by isotope-selective laser photodetachment (ISLP-AMS) was proposed, including development of a high performance pulsed injection-locked Ti:Sapphire laser and a pulsed negative ion source using laser ablation. Through a prototype experimental device, photodetachment of pulsed negative iodine ion was demonstrated and the basic performance was made clear. These results have shown that the negative iodine ion source and the injection-locked Ti:Sapphire laser are well-suited to trace analysis of ^I by ISLP-AMS.
