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).
The motion system has to be as light as possible and as small as possible since everyhting must take place inside the camera.
In addition, the whole system is installed at the top of a Canary Island (difficult accessibility) and must have a lifespan of 15 years. Consequently a grease-free system with restricted maintenance was required.
Due to very limited maintenance actions to set up and long-life products we carefully selected using the on-line configurator, we foresee a cost reduction which is sensible if one takes into account the 9 systems that will equip the 9 cameras for 15 years.
