	The European X-ray Free Electron Laser (EXFEL) uses large undulator systems with a total length of approximately 500 meters. The main part of the system is 91 5m long undulator segments. All segments are gap variable planar undulators. In the next 2 to 3 years all these 91 undulators will be manufactured and subsequently measured and tuned in order to meet the EXFEL field specifications. In order to match the tight schedule and to reach the high qualification, fast and reliable measurement methods and fine tuning algorithms must be established and be tested before the mass production starts. In this paper we report the tuning results of the undulator prototype for the EXFEL. It is shown that good quality is achieved which satisfies all specification asked by the European XFEL. It is also shown that the measurement and tuning procedures work well, fast and are straightforward to apply.

The European X-ray Free Electron Laser (EXFEL) uses large undulator systems with a total length of approximately 500 meters. The main part of the system is 91 5m long undulator segments. All segments are gap variable planar undulators. In the next 2 to 3 years all these 91 undulators will be manufactured and subsequently measured and tuned in order to meet the EXFEL field specifications. In order to match the tight schedule and to reach the high qualification, fast and reliable measurement methods and fine tuning algorithms must be established and be tested before the mass production starts. In this paper we report the tuning results of the undulator prototype for the EXFEL. It is shown that good quality is achieved which satisfies all specification asked by the European XFEL. It is also shown that the measurement and tuning procedures work well, fast and are straightforward to apply.
