For a fundamental research project in the field of astroparticle physics, a calibration device based on a 40cm-wide white screen is attached on a so-called XY table. This table is made out of two 2.4m-long parallel ZLW-1040 that are connected with a third 2.2m-long ZLW-1080. The assembly takes place inside a 3m*3m Cherenkov camera of a telescope which focal distance is 16m. At total, 9 NectarCAM will equip 9 telescopes among the whole array (Cherenkov Telescope Array Observatory).
