INFN-LNS K800超导回旋加速器的原有聚束器设置在加速器磁轭内部,距离中心平面0.5 m处。考虑装配及维护便利,在靠近加速器下盖板处设计了新聚束器取代原有设计。新聚束器采用三电极结构,电极间隙5 mm,中间电极长83.5 mm,工作频率范围15~50 MHz,聚束电压60~110 V。聚束器设计为正弦波功率信号驱动,通过feedthrough连接聚束器中间电极和匹配网络,整体结构如图1所示。
The original beamformer of the INFN-LNS K800 superconducting cyclotron was placed inside the yoke of the accelerator at a distance of 0.5 m from the center plane. Considering the ease of assembly and maintenance, a new condenser was designed near the accelerator undercover to replace the original design. The new beam-erector features a three-electrode structure with 5 mm electrode gap, 83.5 mm middle electrode length, 15-50 MHz operating frequency and 60-110 V bunching voltage. The buncher is designed to be driven by a sine wave power signal and is connected by feedthrough to the middle electrode of the buncher and to the matching network. The overall structure is shown in Figure 1.
