Resumen:

A 14 mm - 10 period NbTi superconducting undulator for the next generation of Free Electron Laser has been studied. The optimum electromagnetic pre-design was carried out using RADIA, an extension module of the commercial software Mathematica. For this pre-design, a variable gap was considered. Additionally, a thermo-mechanical study of one eighth of the superconducting undulator was conducted. This study utilized a thermal and mechanical contact model between the pancake coils and the carbon steel core. This coupled model allowed estimating the minimum pre-loading of the coil. This pre-loading ensures that the coil would remain stuck to its pole during cooling. Numerical results are presented for both studies. © Proceedings of the 38th International Free-Electron Laser Conference, FEL 2017. All rights reserved.
