Study on Thermal Analysis of Dome in LAMOST

Abstract:

LAMOST（Large Sky Area Multi-Object Fiber Spectroscopic Telescope）is a breakthrough on astronomy in China, and is also in the lead on astronomy in the world. During the design, the seeing of telescope LAMOST is one of the most important aspects. While the temperature difference in the dome is the significant factor that affects the seeing, the temperature distribution in the dome must be controlled. The thermal distribution of the dome in telescope LAMOST was calculated and simulated by Icepak software. The emulation demonstrates that without any cooling project, the discipline of the temperature distribution in the dome around the first mirror Ma is nice enough to achieve a good seeing while the mirror Ma is in the partly open globular structure. According to these results, there is no need to working out a cooling scheme to improve the thermal circumstances of the dome. The result of emulation is approximate to the experiment temperature distribution of the Ф2.16m telescope that is closely near to the LAMOST, which makes significance to improve the seeing of the dome and to develop the dome’s design.
