  In undulator systems with variable gaps phase shifters are needed to exactly match the phase between individual segments so that constructive superposition of the emitted light occurs. A phase shifter based on Permanent Magnet technology for the use in the European XFEL has been developed and tested. This paper will explain its magnetic principle and focus on the applied correction schemes and the presentation of the final results.
