    Deformation tests by inserting “Dummies”



    ESO ,Gottingen, and CRAL, chose to insert « 24 Dummies » mass of 86 kg (without cables DV)to simulate the 24 IFU on the structure of the IMS to the instrument MUSE to identify possible deformations that may cause misalignment of optical see the instrument itself. The test result shows that no deformation occurred. Using the insertion tool “IFU POSITIONNING TOOL” and crane is a precise and meticulous operation. This integration has allowed us To identify and correct troublesome obstacles to the integration of IFU To define a procedure to insert the IFU (to be validated on a real IFU).
