Abstract :
We present the results of the commissioning of the first elliptically polarizing undulator (EPU) to be installed at the 1.37 GeV electron storage ring of the Brazilian synchrotron light source (LNLS). The undulator is designed to provide UV and soft X-ray photons from 100 eV up to 1 keV with full polarization control. It uses the APPLE II design and allows for both parallel and anti- parallel longitudinal motion of its magnet cassettes. We present the commissioning results including the measured orbit and tune perturbations of the undulator fields on the stored beam.
