The Horizontal-Gap Vertically-Polarizing Undulator (HGVPU) is a compact, innovative, variable-gap insertion device developed by Argonne National Laboratory for the LCLS-II HXR beamline at SLAC. A full sized 3.4-meter-long prototype has been built and fully tested meeting all LCLS-II undulator specifications. An array of conical springs compensates the attractive magnetic forces of the undulator jaws. These springs are designed to exhibit non-linear spring characteristics that can be closely tuned to match the force curve exerted by the magnetic field, thereby minimizing the overall deflection of the strongbacks. The HGVPU also utilizes the existing LCLS-I support and motion system along with other existing equipment and infrastructure, thus lowering overall cost and installation downtime.
