“…After finalising a prototyping phase in which the most critical aspects of the mechanical concept have being tested and qualified, EMIR is now entering into the fabrication and AIV phase. The full details of the mechanical design can be found in the reference list 7,8,9,10 . The EMIR mechanical desing relays on the development of a fully cryogenic robotic system which can be remotely reconfigured to form the multi-slit pattern in the instrument focal plane, and which is referred to as CSU along this paper.…”

“…The wheels and the DTU can be seen in Figure 5 together with many details of the EMIR mechanical design. The current status of the mechanical development is described elsewhere in this proceedings 10 . It is worth to mention that the project has recently reviewed the results of the prototype test in an Advanced Review Meeting which has concluded sucesfully.…”

EMIR, currently entering into its fabrication and AIV phase, will be one of the first common user instruments for the GTC, the 10 meter telescope under construction by GRANTECAN at the Roque de los Muchachos Observatory (Canary Islands, Spain). EMIR is being built by a Consortium of Spanish and French institutes led by the Instituto de Astrofísica de Canarias (IAC). EMIR is designed to realize one of the central goals of 10m class telescopes, allowing observers to obtain spectra for large numbers of faint sources in an time-efficient manner. EMIR is primarily designed to be operated as a MOS in the K band, but offers a wide range of observing modes, including imaging and spectroscopy, both long slit and multiobject, in the wavelength range 0.9 to 2.5 µm. It is equipped with two innovative subsystems: a robotic reconfigurable multislit mask and disperssive elements formed by the combination of high quality difracction grating and conventional prisms, both at the heart of the instrument. The present status of development, expected performances, schedule and plans for scientific exploitation are described and discussed. The development and fabrication of EMIR is funded by GRANTECAN and the Plan Nacional de Astronomía y Astrofísica (National Plan for Astronomy and Astrophysics, Spain).

“…The EMIR mechanical design 13,14,15,16 relays on the development of a fully cryogenic robotic system which can be remotely reconfigured to form the multi-slit pattern in the instrument focal plane, the CSU, which has been subject to a development and manufacturing contract and is pending of its final acceptance at the IAC, which should happen in the forthcoming weeks. Several functional prototypes have been produced along during the development phase, which has been tested intensively to optimize the concept.…”

EMIR is one of the first common user instruments for the GTC, the 10 meter telescope operating at the Roque de los Muchachos Observatory (La Palma, Canary Islands, Spain). EMIR is being built by a Consortium of Spanish and French institutes led by the Instituto de Astrofísica de Canarias (IAC). EMIR is primarily designed to be operated as a MOS in the K band, but offers a wide range of observing modes, including imaging and spectroscopy, both long slit and multiobject, in the wavelength range 0.9 to 2.5 μm. This contribution reports on the results achieved so far during the verification phase at the IAC prior to its shipment to the GTC for being commissioned, which is due by mid 2015. After a long period of design and fabrication, EMIR finally entered into its integration phase by mid 2013. Soon after this, the verification phase at the IAC was initiated aimed at configuring and tuning the EMIR functions, mostly the instrument control system, which includes a sophisticated on line data reduction pipeline, and demonstrating the fulfillment of the top level requirements. We have designed an ambitious verification plan structured along the three kind of detectors at hand: the MUX and the engineering and scientific grade arrays. The EMIR subsystems are being integrated as they are needed for the purposes of the verification plan. In the first stage, using the MUX, the full optical system, but with a single dispersive element out of the three which form the EMIR suite, the two large wheels mounting the filters and the pseudo-grisms, plus the detector translation unit holding the MUX, were mounted. This stage was mainly devoted to learn about the capabilities of the instrument, define different settings for its basic operation modes and test the accuracy, repeatability and reliability of the mechanisms. In the second stage, using the engineering Hawaii2 FPA, the full set of pseudo-grisms and band filters are mounted, which means that the instrument is fully assembled except for the cold slit unit, a robotic reconfigurable multislit mask system capable of forming multislit pattern of 55 different slitlets in the EMIR focal plane. This paper will briefly describe the principal units and features of the EMIR instrument as the main results of the verification performed so far are discussed. The development and fabrication of EMIR is funded by GRANTECAN and the Plan Nacional de Astronomía y Astrofísica (National Plan for Astronomy and Astrophysics, Spain).
