摘要
BULLKID-DM 实验旨在探测质量低于 GeV/ 的类 WIMP 暗物质粒子。探测这些粒子具有挑战性，因为需要具有高暴露度和约 100 eV 能量阈值的核反冲探测器，从而超出常规半导体探测器的能力。BULLKID-DM 通过使用具有异常低能量阈值的 cryogenic 动量电感探测器 (MKID) 来应对这一挑战，探测器总质量为 800 g，分为 16 个晶圆，包含超过 2000 个 individually 仪器化的硅骰子。每个晶圆上的 MKID 耦合到单个传输线，并通过室温数据采集系统采用频率复用方法进行读出。在本文中，我们描述并评估了室温读出电子系统的设计，包括所选硬件组件和包含 tone 生成、频率解复用和事件触发等实时信号处理阶段的 FPGA 固件。我们在 ZCU216 板上对系统进行评估，该板是基于具有集成高速 DAC 和 ADC 的射频 System-on-Chip (RFSoC) 的商业评估卡，并连接到我们设计的自定义模拟前置放大器用于信号调理。
