| Abstract |
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.
