Abstract

A laser (Nd:YAG laser, 3 J, 1064 nm, 8-10 ns) ion source has been built and under development at IMP to provide pulsed high-charge-state heavy ion beams to a radio frequency quadrupole (RFQ) for upgrading the IMP accelerators with a new low-energy beam injector. The laser ion source currently operates in a direct plasma injection scheme to inject the high charge state ions produced from a solid target into the RFQ. The maximum power density on the target was about 8.4 × 10(12) W∕cm(2). The preliminary experimental results will be presented and discussed in this paper.

摘要

中国科学院近代物理研究所已建成并正在开发一种激光（钕：钇铝石榴石激光，3焦耳，1064纳米，8 - 10纳秒）离子源，用于为射频四极杆（RFQ）提供脉冲高电荷态重离子束，以用新型低能束注入器升级近代物理研究所的加速器。该激光离子源目前采用直接等离子体注入方案，将固体靶产生的高电荷态离子注入到RFQ中。靶上的最大功率密度约为8.4×10(12)瓦∕平方厘米。本文将介绍并讨论初步实验结果。
