电子回旋加速器源（ECR）电荷增殖器最初是为放射性离子束生产而开发的，其表明在ECR离子源内部的初级束的束注入是用于束生产的非常一般的过程。在这篇文章中，我们将审查的ISN格勒诺布尔实验台上获得的最新结果，生产顺时针（CW）或脉冲金属离子束与所谓的“1+/n+”的方法。对于CW操作给出了新的结果，其中效率对于多电荷放射性离子产生的应用特别优化（例如，对于Zn 1 +→ Zn 9+为3.5%，对于Pb 1 +→ Pb 24+为4.2%，对于Rb 1 +→ Rb 15+为5%）。不同的离子源已被用来研究作为1+初级束的能量的函数的效率的变化。电荷态分布，特别是测量铅和Rb离子。一种新的操作模式，电子回旋共振离子阱增殖器/聚束器，它允许捕获和聚束的n+离子束的演示和实验…
Initially developed for radioactive ion beam production, the electron cyclotron resource (ECR) charge breeder shows that the beam injection of a primary beam inside an ECR ion source is a very general process for beam production. In this article we will review the latest results obtained on the ISN Grenoble test bench for the production of clockwise (CW) or pulsed metallic ion beams with the so-called “1+/n+” method. New results are given for CW operation where the efficiency is particularly optimized for application to multicharged radioactive ion production (for example, 3.5% for Zn1+→Zn9+, 4.2% for Pb1+→Pb24+, 5% for Rb1+→Rb15+). Different ion sources have been used to study the variation of the efficiency as a function of the energy of the 1+ primary beam. Charge state distributions are especially measured for Pb and Rb ions. A new mode of operation, the electron cyclotron resonance ion trap breeder/buncher, which permits the trapping and the bunching of the n+ ion beam is demonstrated and experimenta...
