星系外背景光（EBL）是来自银河系外所有物体的综合发射。受恒星发射历史的影响，近红外波段的EBL将光追溯到宇宙中第一批恒星的诞生，并可以对结构形成模型进行严格的约束。最近利用斯皮策太空望远镜和第一次宇宙红外背景实验（CIBER-1）的数据进行的研究发现，在大尺度上，EBL中存在过多的波动，这些波动要么归因于高红移星系和类星体，要么归因于在合并事件中从宿主星系中剥离的恒星。为了帮助区分这两个模型，可以使用多波长数据来追踪它们独特的光谱特征。继CIBER-1的成功之后，CIBER-2的设计目的是利用覆盖光学和近红外的六个波段的数据来识别EBL过度波动的来源。该实验包括低温有效载荷，计划在可回收探空火箭上发射四次。CIBER-2配有28.5 cm望远镜和光学系统，可同时获得0.5 ~ 2.5 μm 6个广谱带的宽视场图像。实验采用2048 × 2048夏威夷- 2rg探测器阵列和低温星跟踪器。低温恒星跟踪器的原型正在建造中，用于单独发射，以验证其性能和恒星跟踪算法。到2018年中期，CIBER-2实验的机械、光学和电气组件将集成到有效载荷中。在这里，我们介绍了CIBER-2的最终设计和我们团队的仪器表征工作。讨论了光学聚焦测试的设计和分析。我们还报告了CIBER-2支持系统的性能，包括冷却机制和可部署组件。最后，我们概述了准备发射有效载荷所需的剩余任务。
The extragalactic background light (EBL) is the integrated emission from all objects outside of the Milky Way galaxy. Imprinted by the history of stellar emission, the EBL in the near infrared traces light back to the birth of the first stars in the Universe and can allow tight constraints on structure formation models. Recent studies using data from the Spitzer Space Telescope and the first Cosmic Infrared Background ExpeRiment (CIBER-1) find that there are excess fluctuations in the EBL on large scales which have been attributed to either high redshift galaxies and quasars, or to stars that were stripped from their host galaxies during merging events. To help disentangle these two models, multi-wavelength data can be used to trace their distinctive spectral features. Following the success of CIBER-1, CIBER-2 is designed to identify the sources of the EBL excess fluctuations using data in six wavebands covering the optical and near infrared. The experiment consists of a cryogenic payload and is scheduled to launch four times on a recoverable sounding rocket. CIBER-2 has a 28.5 cm telescope coupled with an optics system to obtain wide-field images in six broad spectral bands between 0.5 and 2.5 μm simultaneously. The experiment uses 2048 × 2048 HAWAII-2RG detector arrays and a cryogenic star tracker. A prototype of the cryogenic star tracker is under construction for a separate launch to verify its performance and star tracking algorithm. The mechanical, optical, and electrical components of the CIBER-2 experiment will have been integrated into the payload by mid-2018. Here we present the final design of CIBER-2 and our team’s instrument characterization efforts. The design and analysis of the optical focus tests will be discussed. We also report on the performance of CIBER-2 support systems, including the cooling mechanisms and deployable components. Finally, we outline the remaining tasks required to prepare the payload for launch.
