  As part of the LEAPS*-INNOV** pilot project, Task 5.2 is dedicated to interferometers based online metrology developments applied to photon science instrumentation. One of the main objectives of Task 5.2 is to explore and develop the possibilities offered by interferometers (in particular fiber connected systems) to measure the sample position and its motions during typical synchrotron experiments. This four year program started in April 2021, with the participation to Task 5.2 of ALBA-CELLS, ESRF, HZB, PTB and SOLEIL. The objective of the poster is diffuse information on Task 5.2 current plans and to gather information on existing / on-going works and possible collaborations in the field of interferometers based metrology. *LEAPS: The League of European Accelerator-Based Photon Sources **LEAPS-INNOV is a pilot project submitted in reply to the INFRAINNOV-04-2020 European Union call for the implementation of open innovation and new strategies and tools for partnership with industry within the photon science community. It involves in particular the European synchrotron radiation light sources and free electron laser large-scale research infrastructures.

  The MARS beamline*, operating at SOLEIL since 2010, has been developed to provide researchers with advanced X-ray techniques to characterize nuclear materials. The diversity in users’ demands has driven the development of the most suitable detector support to accommodate novel experiments that have not been specified at the time of design. The choice complied with constraints related to the installation in a narrow experimental hutch along with easy transport and maintenance. The system consists of a long-range linear table (Ts) mounted on a wide angular (-1° ; +65°) Rx rotation; Rx can be moved off the beam axis (Tx) to align the detector with the transmitted/reflected beam. It accommodates for any detector by only changing the kinematic interface with Ts. It is worth remarking on the wide angular range with a potential concentration of mass at the end of the arm (payload : 55 kg). FEA was done to study its structural behavior. Performing movements with low SOC values not only puts constraints on the mechanics, but also on control system. As such, Delta Tau Powerbrick controller has been implemented. The design project is complete and built with commissioning work to be done.
