The production of radioactive ions using the Isotope Separation On-Line method gives rise, in most cases, to singly charged ions. In order to perform experiments with postaccelerated radioactive ion beams, these ions have to be multicharged. We describe here a new compact design for a charge breeder that will be coupled to the production target of SPIRAL1 at GANIL. We present recent results obtained offline with stable alkali ions (Na, K, Rb, and Cs) on the SIRa test bench. Particularly, 1(+) to N(+) conversion efficiencies and conversion times are presented. Several points have been identified for the improvements of the present performances.
采用在线同位素分离方法产生放射性离子，在大多数情况下会产生单电荷离子。为了进行后加速放射性离子束实验，这些离子必须多电荷化。我们在此描述一种电荷增殖器的新型紧凑设计，它将与GANIL的SPIRAL1生产靶耦合。我们展示了最近在SIRa试验台上用稳定碱金属离子（钠、钾、铷和铯）获得的离线结果。特别给出了1（+）到N（+）的转换效率和转换时间。已经确定了几个改进当前性能的要点。
