标题： Lifetime study of the ColdADC for the Deep Underground Neutrino Experiment

摘要： 冷ADC是一种定制的ASIC数字化器，采用65纳米CMOS技术实现，使用专门的技术以确保在低温环境下的长期可靠性。 冷ADC是为DUNE远探测器综合体开发的，该综合体将由四个液氩时间投影室组成。 每个探测器含有17千吨液氩作为靶材料，以测量中微子振荡。 大约40,000个冷ADC ASIC将在DUNE的前两个大型探测器中安装，并在实验期间在低温下运行，且无需更换。 冷ADC的寿命是影响实验数据质量和物理灵敏度的关键参数。 对冷ADC寿命的测量已经进行，本文中展示的结果表明，冷ADC的寿命比探测器计划运行时间长几个数量级。 显示英文摘要

摘要： ColdADC is a custom ASIC digitizer implemented in 65 nm CMOS technology using specialized techniques for long-term reliability in cryogenic environments. ColdADC was developed for use in the DUNE Far Detector complex, which will consist of four liquid argon time projection chambers. Each contains 17 kilotons liquid argon as the target material in order to measure neutrino oscillations. Approximately 40,000 ColdADC ASICs will be installed for DUNE in the first two large detectors and will be operated at cryogenic temperatures during the experiment without replacement. The lifetime of the ColdADC is a critical parameter affecting the data quality and physics sensitivity of the experiment. A measurement of the lifetime of the ColdADC was carried out, and the results shown in this paper assure orders of magnitude longer lifetime of the ColdADC than the planned operation time of the detectors.
