摘要
当前旨在测量宇宙微波背景（CMB）偏振的实验使用低温探测器阵列和冷光学系统以提高巡天测绘速度。因此，需要具有大光学窗口、可连续工作数年的大体积低温系统。本文报道 QUBIC（宇宙学 Q 和 U 玻色干涉仪）实验的低温系统：我们描述了其在技术验证装置配置下的设计、制造、实验优化与验证。QUBIC 低温系统基于一个大体积低温恒温器，使用两台脉冲管制冷机将大（约 1 m^3）、重（约 165kg）的仪器冷却至约 3K，该仪器包括低温偏振调制器、波纹馈源喇叭阵列以及更低温度级；一个 4He 蒸发器将干涉仪光束合成器冷却至约 1K；一个 3He 蒸发器将焦平面探测器阵列冷却至约 0.3K。该低温系统已通过并验证超过 6 个月的连续运行。探测器阵列达到 0.33K 的稳定工作温度，而偏振调制器在约 10K 的基准温度下运行。系统已倾斜以覆盖 20 度至 90 度的视轴仰角范围，且无显著温度变化。该仪器现已准备部署至阿根廷高安第斯山脉。
