摘要
介绍了在兰州近代物理所建设的兰州重离子加速器冷却储存环外靶实验读出电子学预研系统中触发系统的需求特点以及基于PXI(PCI eXtensions for Instrumentation)总线规范进行触发系统的设计研究。触发系统根据高能物理实验特点将各探测器的电子学通道输入信号进行分级处理,产生携带触发信息的次级触发信号上传至上一级触发处理模块,并最终结合整个系统的各子触发信号,产生最终的触发信号发送至各子探测器系统用于触发判选。通过与探测器进行的联合调试,验证了基于PXI总线构架的触发系统的功能和指标,并为完整系统的设计和扩展提供了一个重要的参考。
The paper is to introduce the research on the trigger system of CSR readout electronics which are based on the PXI bus. The trigger system consists of different trigger levels according to the trigger signals charaeters in the high energy physics experiments. The final trigger, what is the envent trigger, comes from the former trigger level signals, which stand for different physics actions. The trigger system then will fan out the final trigger to subsystems to choose the opposite data. Being testted with the whole detector system, the mini trigger system works well with good preformance in functions. It will be a good example for the future whole electronic system.
