摘要

In these proceedings we give a summary of the characteristics and current status of the MEGARA instrument,the future optical IFU and MOS for the 10.4-m Gran Telescopio Canarias (GTC). MEGARA is being builtby a Consortium of public research institutions led by the Universidad Complutense de Madrid (UCM, Spain)that also includes INAOE (Mexico), IAA-CSIC (Spain) and UPM (Spain). The MEGARA IFU includes twodifferent fiber bundles, one called LCB (Large Compact Bundle) with a field-of-view of 12.5×11.3 arcsecsup2/sup anda spaxel size of 0.62 arcsec yielding spectral resolutions between R=6,800-17,000 and another one called SCB(Small Compact Bundle) covering 8.5×6.7 arcsecsup2/sup with hexagonally-shaped and packed 0.42-arcsec spaxels andresolutions R=8,000-20,000. The MOS component allows observing up to 100 targets in 3.5×3.5 arcminsup2/sup. Boththe IFU bundles and the set of 100 robotic positioners of the MOS will be placed at one of the GTC Folded-Cassfoci while the spectrographs (one in the case of the MEGARA-Basic concept) will be placed at the Nasmythplatform. On March 2012 MEGARA passed the Preliminary Design Review and its first light is expected totake place at the end of 2015.© (2012) COPYRIGHT Society of Photo-Optical Instrumentation Engineers (SPIE).
