论文摘要
Atlas 1级热量计触发的预处理器通过数字化，同步和校准它们来重建横向能量沉积物，从而准备从Atlas量热计发送的模拟触发信号，然后将其用于进一步处理以识别事件特征。在2013年至2014年的LHC的第一次长时间关闭中，预处理器的中心组成部分Multichip模块被升级的版本取代，这些版本具有现代ADC和FPGA技术，以确保LHC运行2的高堆环境中的最佳性能2。本文介绍了新的Multichip模块的特征，并介绍了该信号的特征，并与该交通相处得出了这些信号。
The PreProcessor of the ATLAS Level-1 Calorimeter Trigger prepares the analogue trigger signals sent from the ATLAS calorimeters by digitising, synchronising, and calibrating them to reconstruct transverse energy deposits, which are then used in further processing to identify event features. During the first long shutdown of the LHC from 2013 to 2014, the central components of the PreProcessor, the Multichip Modules, were replaced by upgraded versions that feature modern ADC and FPGA technology to ensure optimal performance in the high pile-up environment of LHC Run 2. This paper describes the features of the new Multichip Modules along with the improvements to the signal processing achieved.
