介绍了北京谱仪III(BESIII)电磁量能器触发系统的触发单元和块能量相加(TCBA)板的设计、硬件实现和测试结果。该板主要完成对触发单元信号的甄别以便进行簇团的计数,并且提取电磁量能器的时间信息,同时将触发单元能量进一步相加形成块能量信息。着重介绍了块能量相加、时间信息提取部分的设计和时间信息晃动的测试结果。
The design, hardware implementation and test results of the triggering unit and the block energy addition (TCBA) board of BESIII electromagnetic energy trigger system are introduced. The board mainly finishes the screening of the signal of the triggering unit to count the clusters and extracts the time information of the electromagnetic energy measurer while further adding the triggering unit energy to form the block energy information. Emphasis is given to the block energy addition, time information extraction part of the design and time information shaking test results.
