A universal adjustment platform to position the High Luminosity LHC components according to 6 degrees of freedom

摘要

A universal adjustment platform has been developed to position accelerator components with a weight below 2 t. It will control 6 degrees of freedom with a displacement resolution of each axis within 10 μm. The objective of such a platform is to simplify the process of adjustment that can be fastidious and time-consuming. For this Stewart-based platform, the kinematics has been optimized in such a way that all the displacement axes are independent, leading to an intuitive adjustment. All the adjustment knobs are located on the same side, with a possibility to plug temporary motors or even permanently installed motors. Two models of platform have been developed for components lighter than 300 kg or heavier - between 300 and 2000 kg. The two prototypes are presented with a focus on the results of the validation tests.
