Abstract :
The first insertion device built at LNLS was an elliptically polarized undulator, designed to cover the vacuum ultraviolet and the soft X-ray spectrum. Its magnetic characterization was done using two techniques: Hall probes, for local field measurements, and rotating coil, operating in a way similar to flip-coil, to determine the integrated multipoles. Final results for the phase errors as well as the procedures used to correct the integrated multipoles are presented.
