【摘要】:高压缩重子物质(Compressed Baryonic Matter,CBM)实验装置飞行时间谱仪利用由多气隙电阻板室(Multi-gap Resistive Plate Chamber,MRPC)探测器构建的超级模块实现高密度、高精度的粒子飞行时间测量,该超级模块可支持高达320通道的高精度时间测量能力,数据率高达6 Gbit·s~(-1)。为实现超级模块探测器的性能评估,提出一种基于千兆以太网的分布式数据读出方法,利用片上系统技术实现读出节点的千兆网络传输能力。测试结果表明,针对单条数据传输路径,原型读出模块在全链路情况下,能实现约467 Mbit·s-1的综合数据传输速率。读出方案中事例组装、命令发送、状态显示等功能均运行正常。
[Abstract]:The time-of-flight spectrometer, an experimental device of compressed baryon matter (CBM), uses a super module constructed from a multi-gap resistor chamber, Multi-gap Resistive Plate (MRPC) detector, to achieve high density and high precision particle time-of-flight measurement. This super module can support the high precision time measurement ability of up to 320 channels, and the data rate is up to 6 Gbit 路sb-1. In order to realize the performance evaluation of the super module detector, a distributed data readout method based on gigabit Ethernet is proposed. The test results show that for a single data transmission path, the prototype readout module is in the case of a whole link. The integrated data transmission rate of about 467 Mbit 路s-1 can be realized. The functions of case assembly, command sending and status display in the readout scheme are all running normally.
