Commissioning of the LNLS elliptically polarizing undulator
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 longi
