| Popis: | Ground-based and airborne instrumentation for astronomy IX (2022), Montreal, jul 17-22, 2022.--Proceedings of SPIE - The International Society for Optical Engineering vol. 12184 Article number 121842B The Sunrise Chromospheric Infrared spectroPolarimeter (SCIP) is an instrument for the third flight of the Sunrise balloon-borne solar observatory planned for 2022. To verify the high spatial and spectral resolutions required in the balloon flight, the SCIP optical unit was subjected to a thermal-vacuum test in which the SCIP optical unit was installed in a vacuum chamber and was exposed to the thermal vacuum environment expected in the balloon flight. We verified the heater control performance and the temperature distribution in the SCIP optical unit in hot and cold conditions created by the shrouds in the vacuum chamber. We confirmed the optical performance, such as spatial and spectral resolution, and an air-to-vacuum difference of the optics by injecting the laser and white lights through a vacuum window. The Sunrise III balloon project is funded in Japan by the ISAS/JAXA Small Mission-of-Opportunity program for novel solar observations and JSPS KAKENHI Grant Number 18H05234 (PI: Y. Katsukawa). We would also thank the significant technical support given by the Advanced Technology Center (ATC), NAOJ. The Spanish contribution to Sunrise III has been supported by the Spanish Ministry of Science and Innovation through projects and ESP-2016-77548-C5-1-R and RTI2018-096886-B-C51 by "Centro de Excelencia Severo Ochoa" Program under grant SEV-2017-0709. D.O.S. also acknowledges financial support through the Ramon y Cajal fellowship. The German contribution to Sunrise III is funded by the Max Planck Foundation, the Strategic Innovations Fund of the President of the Max Planck Society (MPG), the Deutsches Zentrum fur Luft und Raumfahrt (DLR), and private donations by supporting members of the Max Planck Society, which is gratefully acknowledged. |
