激光溅射法在射频离子阱中产生和囚禁低能多电荷离子

Production and Storage of Low energy Multiply charged Ions by Laser Ablation in a RF Ion Trap

用激光溅射金属氧化物的方法在射频离子阱中产生了Ｃｏ和Ｔｉ的多电荷离子，结合离子阱选择囚禁技术和垂直交叉离子束碰撞冷却方法，得到了稳定囚禁的低能（电子伏特能量）Ｃｏ３＋和Ｔｉ４＋离子。

Multiply charged Co and Ti ions have been produced by means of laser ablation from metal oxides targets in a RF ion trap. With cooling collision of two separated crossed ion beams at right angles and the selective trapping, the low energy (electron volt) Co 3+ and Ti 4+ ions were successfully produced and stably stored in the trap.
