  The current girder set of SOLEIL features 4 girder types weighing from 1.85 t to 3 t, with a respective mass payload varying from 4.1 t to 8 t and lengths from 2.40 m to 4.80 m. The smaller size of magnets used for the present version of the SOLEIL upgrade allows a dramatic size and weight reduction of the magnet-girder assemblies. On the other hand, the number of magnets and girders has increased by a factor of 3, implying longer alignment and installation operations. Another constraint is due to the high compactness of the new lattice causing some limitations and access restrictions in the area between girders and tunnel wall. Several setups involving a number of girders from 116 to 212, various magnet layouts and binding systems have been studied. Dynamic and thermal performances have been evaluated by FEA analysis. This approach gives to accelerator physicists the performance of each solution, and thus a great versatility in the choice of the best setup in terms of dynamic and thermal stability. Alignment constraints, installation schedule reducing "dark time" period and economic considerations have also been taken into account during all the design phase.

  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.
