ECLISSE（ECR耦合到激光离子源进行电荷态增强）项目始于1999年，旨在通过激光离子源（LIS）和电子回旋共振（ECR）离子源之间的耦合来获得强带电离子束（脉冲模式）。要研究的要点似乎是 LIS 产生的离子束和 ECR 等离子体之间的耦合效率，以及相对于用于从固体样品产生离子束的标准方法（例如蒸发、溅射），通过 ECRIS 增强可用电荷状态的可能性。计算证实，只要 LIS 的离子能量低于几百 eV，这个概念可能是有效的。将显示计算的主要特征，以及在激光功率密度低于 1011W/cm2 时在离线测试设备中获得的结果。
The ECLISSE (ECR coupled to Laser Ion Source for charge State Enhancement) project started in 1999 with the aim to obtain an intense beam of highly charged ions (pulsed mode) by means of the coupling between a laser ion source (LIS) and an electron cyclotron resonance (ECR) ion source. The major points to be investigated appeared to be the coupling efficiency between the ion beam produced by the LIS and the ECR plasma, as well as the possibility to enhance the available charge state by an ECRIS with respect to the standard methods which are used to produce ion beams from solid samples (e.g., evaporation, sputtering). The calculations have confirmed that this concept may be effective, provided that the ion energy from the LIS is lower than a few hundred eV. The main features of the calculations will be shown, along with the results obtained in the off-line test facility at laser power densities below 1011 W/cm2.
