摘要:

本文评估了用于高亮度LHC(HL-LHC)实验中ATLAS实验薄间隙室(TGC)前端电子组件的商用即供(COTS)电子元件的辐射耐受性。ATLAS实验截至2025年已积累超过450 fb^-1的数据。其亮度升级,HL-LHC计划于2030年开始运行,将在十年内提供3000-4000 fb^-1的数据,导致探测器电子学中显著更高的辐射水平。TGC前端电子的辐射水平估计为总电离剂量(TID)4.1-7.3 Gy,非电离能量损失(NIEL)1.1-2.2 x 10^11 n_1MeV cm^-2。为评估组件在这些条件下的适用性,通过钴-60伽马射线在名古屋大学进行了TID测试,非电离能量损失测试则在神户大学的双极加速器上进行。各种COTS组件,包括SFP+光收发器、时钟抖动清洁器、光纤、电压参考、运算放大器、模拟-数字转换器、数字-模拟转换器、SD卡、闪存存储器和低dropout稳压器,均被测试并评估了所需的辐射水平。结果表明,所有评估的组件均满足TGC前端电子在HL-LHC中的TID和NIEL耐受性要求。

英文摘要:

This paper evaluates the radiation tolerance of commercial off-the-shelf (COTS) electronics components for use in the Thin Gap Chamber (TGC) frontend electronics of the ATLAS experiment at the High-Luminosity LHC (HL-LHC). The ATLAS experiment has accumulated more than 450 fb^-1 of data as of 2025. Its luminosity upgrade, the HL-LHC scheduled to begin operation in 2030, will deliver 3000-4000 fb^-1 over ten years and lead to substantially higher radiation levels in detector electronics. The radiation levels for the TGC frontend electronics are estimated to be 4.1-7.3 Gy in terms of Total Ionizing Dose (TID) and 1.1-2.2 x 10^11 n_1MeV cm^-2 in terms of Non-Ionizing Energy Loss (NIEL). To evaluate component suitability under these conditions, TID tests were conducted using Cobalt-60 gamma rays at Nagoya University, and NIEL tests were performed with the Tandem Accelerator at Kobe University. Various COTS components, including SFP+ optical transceivers, clock jitter cleaners, optical fibers, voltage references, operational amplifiers, analog-to-digital converters, digital-to-analog converters, SD cards, flash memories, and low-dropout regulators, were tested and evaluated against the required radiation levels. The results demonstrate that all evaluated components meet the TID and NIEL tolerance requirements for application in the TGC frontend electronics at the HL-LHC.
