研究了大型强子对撞机实验中一种新的一级硬件触发方法，并建立了原型系统。量热计触发原始数据（~ 5tb /s）被重新组织和时间复用，以便单个处理节点（FPGA）可以访问对应于给定束交叉的整个探测器的数据。这为构建新的触发算法提供了最大的灵活性，这将是确保升级后的大型强子对撞机在非常高的背景下具有足够的触发性能的重要因素。给出了一个测试系统，该系统集成了最终系统的所有关键技术，并演示了时间复用和算法性能。
A novel approach to first-level hardware triggering in the LHC experiments has been studied and a prototype system built. Calorimeter trigger primitive data ( ∼ 5 Tb/s) are re-organised and time-multiplexed so that a single processing node (FPGA) may access the data corresponding to the entire detector for a given bunch crossing. This provides maximal flexibility in the construction of new trigger algorithms, which will be an important factor in ensuring adequate trigger performance at the very high levels of background expected at the upgraded LHC. A test system that incorporates all the key technologies for a final system and demonstrates the time-multiplexing and algorithm performance is presented.
