ATLAS液氩量热仪组一直致力于其触发读出电子设备的升级。作为此次升级的一部分，将引入新的触发器“超级单元”，将触发器读数的粒度增加到运行2的十倍。在生产和安装新电子设备的同时，还在开发超级电池读出的能量和定时测量的校准框架。该框架是通过使用脉冲系统校准运行中获取的数据来建立超级单元脉冲形状和其他参数，即基座电平、一个ADC位的等效横向能量以及用于能量计算的最佳滤波算法的系数。新的硬件已被验证，以满足设计规格使用的框架。还正在开发一种新的模拟量热计，使用新的触发读出系统调试期间获得的校准参数。该模拟考虑了长双极脉冲形状的任何数量的相互作用，每个聚束交叉。这说明了高度真实的时间外堆积效应。
The ATLAS Liquid Argon Calorimeter group has been working on an upgrade of its trigger readout electronics. As part of this upgrade, new trigger" Super Cells" will be introduced, increasing the granularity of the trigger readout by a factor of ten with respect to Run 2. While the production and installation of the new electronics is underway, a calibration framework for the energy and timing measurement of the Super Cell readout is also being developed. The framework is created by using data taken in calibration runs with a pulsing system to establish the Super Cell pulse shape and other parameters, ie pedestal level, equivalent transverse energy for one ADC bit, and coefficients of an optimal filtering algorithm for energy calculation. The new hardware has been verified to meet the design specifications using the framework. A new simulation of the calorimeter, using the calibrated parameters obtained during the commissioning of the new trigger readout system, is also being developed. The simulation takes into consideration the long bipolar pulse shape for any number of interaction per bunch crossing. This accounts for highly realistic out-of-time pileup effect.
