Commissioning of two new insertion devices at ELETTRA

Two new insertion devices have recently been installed in the ELETTRA storage ring: a 3.5 Tesla superconducting multipole wiggler and a Figure-8 permanent magnet undulator. The first is the radiation source for a future X-ray diffraction beamline, while the second is designed to generate photons in the 5-11 eV range for inelastic UV scattering experiments. The impact of these devices on the electron beam dynamics was already studied at the design stage. In this paper initial commissioning results are presented and discussed, including the measured effects on the closed orbit and tune.
