With over 6 million channels, the High Granularity Calorimeter for the CMS HL-LHC upgrade presents a unique data transmission challenge. The ECON ASICs provide a critical stage of on-detector data compression and selection for the trigger path (ECON-T) and data acquisition path (ECON-D) of the HGCAL. The ASICs, fabricated in 65 nm CMOS, are radiation tolerant up to 200 Mrad and require low power consumption: < 2.5 mW/sensor-channel per chip. We report on the first functionality and radiation tests for the ECON-D-P1 full-functionality prototype. We present a comparison of single event effect (SEE) cross sections measured for different methods of triple modular redundancy using test results from the ECON-T-P1 full-functionality prototype.

HGCAL 集中器 ASIC 的首次测试结果：ECON-T 和 ECON-D

用于 CMS HL-LHC 升级的高粒度热量计拥有超过 600 万个通道，带来了独特的数据传输挑战。 ECON ASIC 为 HGCAL 的触发路径 (ECON-T) 和数据采集路径 (ECON-D) 提供探测器上数据压缩和选择的关键阶段。 ASIC 采用 65 nm CMOS 制造，可耐受高达 200 Mrad 的辐射，并且功耗要求低：每个芯片 < 2.5 mW/传感器通道。我们报告了 ECON-D-P1 全功能原型的首次功能和辐射测试。我们使用 ECON-T-P1 全功能原型的测试结果，对不同三重模块冗余方法测量的单粒子效应 (SEE) 横截面进行了比较。
