FAIR 项目要求重离子高电流 RFQ 后的 U 束电流高于 18 ema。测量的强度低了两倍。前端系统中的梁动力学已使用 DYNAMION 代码进行了模拟。制造了具有改进的表面质量和重新设计的匹配部分的新型 RFQ 电极。 RFQ 升级后的束流实验证实了计算出的束流增益。 PACS：29.17.+w，41.75.Lx
The FAIR Project requires an U beam current above 18 emA behind the heavy ion high current RFQ. The measured intensity was a factor of two lower. The beam dynamics in the front-end system has been simulated with the DYNAMION code. New RFQ electrodes with an improved quality of the surface and a redesigned matching section were fabricated. Beam experiments after the RFQ upgrade confirmed the calculated gain in beam current. PACS: 29.17.+w, 41.75.Lx
