Contributed Oral Presentation

In the context of the upgrade to SOLEIL II, a 4th-generation synchrotron, the use of Multi-Bend Achromat lattices significantly reduces natural emittance but requires smaller vacuum chambers (12–16 mm), leading to higher power density on chamber walls with limited cooling space. In some cases, there is no room for crotch absorbers, and chambers must fit between magnet poles with less than 1 mm...
