UNDULATORS
For the low photon energy region, CASSIOPEE uses a HU256 electromagnetic undulator, with a 256 mm period, which was designed at SOLEIL and built at the Budker Institute of Nuclear Physics in Novosibirsk (Russia). This undulator supplies linearly (vertical or horizontal) or circularly (left or right) polarized photon in the 8 eV-100 eV range.
Two undulators are necessary to cover the large photon energy available on CASSIOPEE. They were designed and measured by the SOLEIL Insertion device Group (Antoine Dahl, Oleg Shubar, Fabrice Marteau, Chamseddine Benabderrahmane, Marie-Emmanuelle Couprie and Fabien Briquez).
