title = "Integration and instrument characterization of the cosmic infrared background experiment 2 (CIBER-2)",
abstract = "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.",

Japanese participation was supported by KAKENHI (2034, 18204018, 19540250, 21340047, 21111004, and 15H05744) from Japan Society for the Promotion of Science (JSPS) and the Ministry of Education, Culture, Sports, Science and Technology (MEXT). Korean participation was supported by the Pioneer Project from Korea Astronomy and Space Science Institute (KASI). CSTARS was supported by USIP NASA grant NNX16AI82A. C.H.N was supported by NASA Headquarters under the NASA Earth and Space Science Fellowship Program - Grant 80NSSCK0706. We would like to thank the NASA Wallops Flight Facility engineers and staff for their technical supports. Funding Information: A prototype of this star tracker is named the Cryogenic Star Tracking and Attitude Regulation System (CSTARS-1). CSTARS-1 is funded by a NASA Undergraduate Student Instrument Project (USIP) grant. Its firmware and tracking algorithm are developed by a team of interdisciplinary undergraduate students at the Rochester Institute of Technology (RIT). CSTARS-1 will fly on a separate BB IX mission to gather data that can verify the detector{\textquoteright}s hardware, firmware, and real-time star tracking algorithm. This payload includes a small lens telescope and an sCMOS detector assembly enclosed in a cryostat to keep the detector at 77 K. On-board electronics will read the detector, identify stars and perform the tracking algorithm, then send the pointing information to the rocket{\textquoteright}s attitude control system.
