共振电离激光离子源（RILIS）由于其高效率、速度和无与伦比的选择性，是ISOLDE在线同位素分离器设施电离核反应产物的首选方法。通过利用所选元素的独特电子能级“指纹”，激光分步共振电离的RILIS过程使高化学纯度的离子束能够通过质量选择分离器磁体发送。因此，所选同位素束的同量异位素纯度大大增加。RILIS由多达三个频率可调谐脉冲染料激光器组成，已经升级，安装了Nd：YAG泵浦激光器，以取代旧的铜蒸气激光器（CVL）系统。对目前Nd：YAG泵浦RILIS的性能进行了总结。伴随着RILIS泵浦激光器的升级，一个新的锰离子化方案已在新建的激光共振电离光谱（LARIS）实验室，并成功地应用于在线RILIS操作。LARIS设施的概述是沿着与锰的电离方案开发工作的细节。
On account of its high efficiency, speed and unmatched selectivity, the Resonance Ionization Laser Ion Source (RILIS) is the preferred method for ionizing the nuclear reaction products at the ISOLDE on-line isotope separator facility. By exploiting the unique electronic energy level ‘fingerprint’ of a chosen element, the RILIS process of laser step-wise resonance ionization enables an ion beam of high chemical purity to be sent through the mass selective separator magnet. The isobaric purity of a beam of a chosen isotope is therefore greatly increased. The RILIS, comprising of up to three frequency tunable pulsed dye lasers has been upgraded with the installation of a Nd:YAG pump laser as a replacement for the old Copper Vapor Laser (CVL) system. A summary of the current Nd:YAG pumped RILIS performance is given. To accompany the RILIS pump laser upgrade, a new ionization scheme for manganese has been developed at the newly constructed LAser Resonance Ionization Spectroscopy (LARIS) laboratory and successfully applied for on-line RILIS operation. An overview of the LARIS facility is given along with details of the ionization scheme development work for manganese.
