During the first half of 2018 we have built and fully qualified the Engineering Qualifying Model (EQM). This model contained a real fully coated filter and served to completely validate the design of the FWA both in the terms of structural and alignment performance and the validation of the simulations and the optical performance of the filers. The group had to fully commission the Ground Segment Equipment, including an x-y metrology table with the confocal sensor to allow the precise non-contact metrology of the FWA, the interferometer to measure the Wave Front Errors of the filters and the Autocollimator to precisely measure the tip-tilt angle of the filter with respect to the NISP reference surface. All these measurements have been done at operational conditions with the FWA inside the cryostat.
After the successful qualification of the EQM model, we have built and tested (with the same procedures as for the EQM) the Flight Model (FM) that was successfully delivered to the Laboratoire d’Astrophysique de Marseille (LAM), where it was integrated in the NISP-FM. It is expected that the NISP verification tests are done during the first half of 2019 allowing to deliver the NISP Flight Model to ESA in the second half of 2019.
We have also manufactured three spare mounts with their fully flight qualified filters that are kept inside a nitrogen filled sealed aluminum box until Euclid is finally launched.
ASTEROID is an H2020 project aiming at enabling Europe to acquire the technology and knowledge necessary to manufacture 2k^2 high performance Infrared Focal Plane Arrays, define the types of products to design and define the strategy to create an industrial manufacturing line of these detectors. IFAE is partnering with companies and institutions in France and Austria to develop a low noise and low dark current detector that will be directly useful for astronomy application in both ground telescopes (ESO) or space telescopes (ESA).
IFAE’s responsibility is in the optical and electrical characterization of the detector. To perform this task, it will reuse some of the equipment developed for the Euclid project, together with a complete new optical setup. Additionally we have reached an agreement with the European Southern Observatory (ESO) which allow us to use their New Generation Controller (NGC) for the test of the Infrared Sensors. This allows IFAE to acquire the know-how in characterizing IR sensors for Astronomy and Space and establishes a possible link of future collaboration with other ESO missions and their world-class telescopes located in the Atacama Desert in Chile.
IFAE is also responsible for the communication inside ASTEROID. More information can be found in asteroidh2020.eu
