These phenomena are the temperature dependency of the material properties, the strong coupling between various fields of physics (thermal, electric and mechanical) and the stress produced by the change of temperature inside the structure. It is shown that the temperature dependency of the material properties has a relatively small ...

In 1962, under the name of IAL-Space, it began real space activities observing the auroras in ultraviolet by sending around twenty sounding rockets, launched mostly from the base of Kiruna (Sweden). IAL-Space was finally recognized in 1975 as a coordinated test installation of the European Space Agency. It moved to Sart Tilman in 1984 to reach more spacious buildings. Subsequently IAL-Space got the status Research Center in 1988, it became a PRODEX Institute and changed its name to CSL in 1992. Lately it has further expanded with the commissioning of a new test facilities like FOCAL 3, FOCAL XXL, enabling to perform tests in the infrared range. Centre spatial de Liège is now a research Centre dedicated to space instrumentation including environmental test facilities and high level laboratories. It works for the European Space Agency (ESA), for the space industry and for regional industries. From the beginning of its more than 50 years long history, CSL develops, assembles, calibrates and/or tests observation instruments and relevant sub-systems capable to operate in a harsh environment, in order to serve the demands of the space science. Space Systems Program focuses its effort to incorporate CSL into the teams dedicated for definition, design, integration and/or ground and in flight calibration of scientific payload missions, mainly under the final authority of the most prestigious Space Agencies (ESA, NASA, JAXA, CNES, BELSPO, …). Today, more than 15 complex pieces of CSL technology have been launched in space, all of them operating nominally. Some of the most significant instruments made by CSL are: S2 / S68 telescope on TD1/ESRO, Halley Multicolor Camera (HMC/GIOTTO), FOC (HST), EIT solar telescope (SOHO), HI (STEREO), SWAP (PROBA 2), optical monitors with OM (Newton), OMC (INTEGRAL) and various contributions on PACS (Herschel), MIRI (JWST), UVS (JUNO) and COROT. In 2011, this strong heritage allows CSL to be awarded with the Extreme UV Imager (EUI) PIship of Solar Orbiter (ESA M1 science mission). For the Future, CSL is involved in the L1 JUICE, L2 ATHENA, M1 Solar Orbiter, M2 EUCLID, M3 PLATO, S1 CHEOPS, S2 SMILE ESA missions as well as the SPP, ICON NASA Missions. CSL is an Academic Member of IAF since 1988. The presentation will concentrate on the development of Space Instruments during this half a century of Space Adventure, focusing on Solar Physics and Space Weather Instruments.Peer reviewe

It will provide full-sun and high-resolution images of the solar corona in the extreme ultraviolet (17.1 nm and 30.4 nm) and in the vacuum ultraviolet (121.6 nm). The validation of the EUI instrument design has been completed with the Assembly, Integration and Test (AIT) of the instrument two-units Qualification Model (QM). Optical, electrical, electro-magnetic compatibility, thermal and mechanical environmental verifications were conducted and are summarized here. The integration and test procedures for the Flight Model (FM) instrument and sub-systems were also verified. Following the Qualification Review, the flight instrument activities were started with the assembly of the flight units. The mechanical and thermal acceptance tests and an end-to-end final calibration in the (E)UV will then be conducted before delivery for integration on the Solar Orbiter Spacecraft by end of 2016.
