Abstract :
The paper describes the design, magnetic computations and measurements of the elliptical undulator HU256 for Synchrotron Soleil (France): the new technology for insertion vacuum chamber has permitted the design of a Bx & Bz dipole closed structure for an electromagnetic undulator. This magnetic design has been realized on the basis of the 2-D, 3-D modeling (Mermaid and RADIA codes), and dependence´s of the magnetic field integrals from the main macroscopic parameters have been obtained. The undulator can work in standard and quasi-periodical modes. The single dipoles and the undulator HU256 were magnetically measured by a Hall probes system. The results of magnetic measurements and computations are compared and analyzed
