在未来高亮度大型强子对撞机 (HL-LHC) 上运行的 ATLAS 探测器的 LAr 热量计的读出电子器件设计需要对整个读出链进行详细模拟，以便找到探测器信号模拟和数字处理的最佳解决方案。由于 LAr 热量计脉冲相对于 LHC 束团交叉时间的持续时间较长，因此需要考虑不合时宜的信号堆积。为此，开发了模拟框架AREUS。它以位精度对模数转换、增益选择和数字信号处理进行建模，包括数字化噪声和详细的电子效应。优化过程中考虑了触发器和对象重建算法。将介绍 AREUS 的软件实现、其主要功能块的概念以及优化注意事项。将相互比较将并行性引入 AREUS 的各种方法。
The design of readout electronics for the LAr calorimeters of the ATLAS detector to be operated at the future High-Luminosity LHC (HL-LHC) requires a detailed simulation of the full readout chain in order to find optimal solutions for the analog and digital processing of the detector signals. Due to the long duration of the LAr calorimeter pulses relative to the LHC bunch crossing time, out-of-time signal pileup needs to be taken into account. For this purpose, the simulation framework AREUS has been developed. It models analog-to-digital conversion, gain selection, and digital signal processing at bit precision, including digitization noise and detailed electronics effects. Trigger and object reconstruction algorithms are taken into account in the optimization process. The software implementation of AREUS, the concepts of its main functional blocks, as well as optimization considerations will be presented. Various approaches to introduce parallelism into AREUS will be compared against each other.
