Paper Abstract

MEGARA (Multi-Espectrógrafo en GTC de Alta Resolución para Astronomía) is an optical Integral-Field Unit and Multi-Object Spectrograph designed for the GTC (Gran Telescopio de Canarias) 10.4m telescope in La Palma. MEGARA project has already passed preliminary design review and the optics critical design review, first-light it is expected to take place at the end of 2016. MEGARA is a development under a GRANTECAN contract. In this paper we summarize the current status of the LN2 open-cycle cryostat which has been designed by the “Astronomical Instrumentation Lab for Millimeter Wavelengths” at the Instituto Nacional de Astrofísica, Óptica y Electrónica (INAOE) and emphasize the key parts of the system that have updated since the Preliminary Design, the main activities related to acceptance, integration, fabrication and maintenance plans which fit into the overall structure of the management plan of MEGARA are also described. The cryogenic work package of MEGARA has completed all the design stages and is ready for its Critical Design Review and then proceed to fabrication.
