UCIRC2：一个用于EUSO-SPB2的红外云监测器
UCIRC2: An Infrared Cloud Monitor for EUSO-SPB2
摘要：
我们描述了芝加哥大学红外相机2（UCIRC 2）的设计和实现，该相机是为了在EUSO-SPB 2飞行（第二代超压气球上的极端宇宙空间观测站）期间监测云层覆盖而建造的。UCIRC 2使用两台红外（IR）相机，分别以10 $μ$ m和12 $μ$ m波长为中心，以跨越热发射峰值的两个波段捕获EUSO-SPB 2下方云层的图像。红外图像每分钟拍摄一次，可以确定望远镜和地面之间的云层高度和覆盖范围。我们讨论了UCIRC 2的设计和构造，包括使模块具有温度和真空弹性的技术和设计原理。此外，我们描绘了图像重建过程和像素的温度校准过程。本文将对未来的超高能空间望远镜的设计和实现提出建议。
英文摘要：
We describe the design and implementation of the University of Chicago Infrared Camera 2 (UCIRC2) built for monitoring cloud coverage during the EUSO-SPB2 flight (the second generation of the Extreme Universe Space Observatory on a Super Pressure Balloon). UCIRC2 uses two infrared (IR) cameras centered on 10$μ$m and 12$μ$m wavelengths to capture images of the clouds beneath EUSO-SPB2 in two bands spanning the thermal emission peak. Taken every minute, the IR images allow the determination of the height and coverage of clouds between the telescope and the ground. We discuss the design and construction of UCIRC2, including the techniques and design principles that make the module temperature and vacuum resilient. Additionally, we delineate the image reconstruction process and the pixel by pixel temperature calibration procedure. This paper will posit design and implementation suggestions for future ultra-high energy space telescopes.
