The production of rare radioactive ion beam (RIB) far from the valley of stability is one of the final purposes of the Spiral2 facility in Caen. The RIB will be produced by impinging a deuteron beam onto a carbon sample to produce a high neutron flux, which will interact with a uranium target. The primary deuteron beam is produced by an ion source based on ECR plasma generation. The deuteron source and the low energy beam transport (LEBT) has been assembled and tested at CEA Saclay. Diagnostics from other laboratories were implemented on the LEBT in order to characterize the deuteron beam produced and compare it to the initial simulations. The ion source has been based on a SILHI-type source, which has demonstrated good performances in pulsed and continuous mode, and also a very good reliability on long term operation. The 5 mA of deuteron beam required at the RFQ entrance is extracted from the plasma source at the energy of 40 kV. After a brief description of the experimental set-up, this article reports on the first beam characterization experiments.
在远离稳定谷的情况下产生稀有放射性离子束（RIB）是位于卡昂的Spiral2装置的最终目标之一。通过将氘核束撞击到碳样品上以产生高中子通量来产生RIB，该中子通量将与铀靶相互作用。初级氘核束由基于电子回旋共振（ECR）等离子体产生的离子源产生。氘核源和低能束传输（LEBT）已在法国原子能委员会萨克莱组装并测试。来自其他实验室的诊断设备已应用于LEBT，以便对产生的氘核束进行表征，并将其与初始模拟结果进行比较。该离子源基于SILHI型源，该源在脉冲和连续模式下均表现出良好的性能，并且在长期运行中具有非常好的可靠性。在射频四极场（RFQ）入口处所需的5毫安氘核束是从能量为40 kV的等离子体源中引出的。在简要描述实验装置之后，本文报告了首次束流表征实验。
