1 SSOLEIL - Synchrotron SOLEIL

The U15 is an in-vacuum undulator designed to operate at room temperature and at 70K. It is the first in-vacuum undulator designed, assembled and which will be used in SOLEIL's storage ring that have support beams for magnets longer than 2 meters. A clear gap is felt in the technologies used for manufacturing and assembling compared to our standard 2m length in-vacuum undulators. This is due, in part, to the tolerances imposed by the maximum phase error admissible in SOLEIL's storage ring. The poster will shine lights on those difficulties from a design and manufacturing point of view.
