欧洲在电荷增殖器方面的努力主要致力于目前和未来的放射性离子束设施。主要项目是欧洲核子研究中心的高强度和能量ISOLDE，GANIL的SPIRAL 2和EURISOL。大多数实验发展由欧洲计划EURONS（欧洲核结构）和EURISOL（欧洲同位素分离在线放射性离子束设施）资助。两种离子源类型（电子束离子源和电子回旋共振离子源）已经被适配为接受离子束的注入和捕获，以便在最短时间内以最高效率增加其电荷。两种电荷增殖器在放射性离子束设施中的使用各有优缺点。研究的最重要的参数是接受（在发射度和强度）的电荷增殖，效率，和一个特定的n+电荷状态，发射度提取的n+束的电荷增殖时间。研究了用于产生1+放射性离子束的不同1+离子源的电荷增殖器参数，建立并测量了电荷增殖器作为特定加速器束线段的调谐过程。
European effort on charge breeders is mainly dedicated to present and future Radioactive Ion Beam facilities. The main projects are High Intensity and Energy-ISOLDE at CERN, SPIRAL2 at GANIL, and EURISOL. Most of the experimental developments are funded by the European programs EURONS (European Nuclear Structure) and EURISOL (European Isotope Separation On-Line Radioactive Ion Beam Facility). Two ion source types (electron beam ion source and electron cyclotron resonance ion source) have been adapted to accept the injection and the capture of an ion beam, in order to increase its charge with the highest efficiency within the shortest time. Both charge breeders have advantages and disadvantages with regard to their use in a Radioactive Ion Beam facility. The most important parameters studied are acceptance (in emittance and intensity) of the charge breeder, efficiency, and charge breeding time of a specific n+ charge state, emittance of the extracted n+ beam. The charge breeder parameters are studied with different 1+ ion sources dedicated to 1+ radioactive ion beam production, and the tuning procedure of the charge breeder as a beam line section of a specific accelerator is established and measured too.
