论文摘要
正在为两台CERN的抗蛋白机，抗蛋白原减速器（AD）和额外的低能量抗抗抗蛋白（Elena）环开发出一种新的强大纵向诊断。纵向诊断通过光纤从低级射频（LLRF）系统接收数据。千兆数据流的实时处理由其计算资源和实时操作系统启用。强度，一束长度和逐圈的测量值可用于束光束。重度梁的强度，动量扩展和平均频率将很快测量。该系统将为设置和监视RF和冷却系统提供必不可少的输入。操作员还将使用它来监视每台机器的性能和抗蛋白链的整体效率。本文显示了数据采集/处理机制和AD的初步束束结果。还提到了将系统导出到配备相同LLRF系统的其他CERN机器的下一步和计划。
A new powerful longitudinal diagnostics is being developed for the two CERN's antiproton machines, the Antiproton Decelerator (AD) and the Extra Low ENergy ANtiproton (ELENA) ring. The longitudinal diagnostics receives data from the Low-Level Radiofrequency (LLRF) system via optical fiber. Real time processing of gigabit data-streams is enabled by its computational resources and real-time operating system. Measurement of intensity, bunch length and turn-by-turn bunch profiles are available for bunched beams. Intensity, momentum spread and average frequency will soon be measured for debunched beams. The system will provide essential input to setup and monitor RF and cooling systems. It will also be used by operators to monitor each machine's performances and the overall efficiency of the antiproton chain. This paper shows the data acquisition/processing mechanism and preliminary bunched beam results for AD. Next steps and plans for exporting the system to other CERN machines equipped with the same LLRF system are also mentioned.
