A novel undulator prototype with a horizontal magnetic field and dynamic compensation of magnetic forces has been recently developed at the APS as a part of the LCLS-II R&D program.

These requirements include limits on the field integrals and phase errors for all operational gaps, and the reproducibility and accuracy of the gap settings. Extensive mechanical testing has resulted in a performance that meets the requirements on the undulator gap setting. The magnetic tuning has been accomplished by applying a set of magnetic shims. As a result, the satisfactory performance of the undulator prototype has been demonstrated.
