| Research Abstract |
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.
