文章亮点

介绍了CLS设备信息，包括30kV高压平台的激光烧蚀离子源、光电检测系统光束线、激光系统和数据采集系统。第一次调试实验，探测4s 2S1/2→ 激光烧蚀离子源产生的离子束（时间长度约为10μs）中Ca的4p 2P3/2（D2）离子跃迁。用约55MHz的典型线宽测量了四种稳定的40,42,44,48Ca同位素的高分辨率光谱，与全球公认的标准CLS设置的光谱相当。提取了42，44，48Ca同位素的同位素位移，即质量数为A和40的同位素的共振频率差异，δν40，A=νA-ν40，与文献值非常一致。

(Color online) Schematic view of the CLS device, the electrodes of the laser ablation ion source (bottom left inset), and the adopted laser system (top right inset). Stable ion bunches with up to 30 keV energy can be delivered into the beamline and overlapped with a continuous-wave frequency-tunable laser beam in an anti-collinear geometry. The ion beam velocity or laser frequency is tuned to resonantly excite the ions in the interaction zone. Fluorescence photons emitted from the excited ions are collected by the photon detection system. See text for more details.
