Abstract :
We present the results of the commissioning of the 10 m long NISUS undulator of the Deep Ultra Violet Free Electron Laser (DUV-FEL) project. The magnet and diagnostics geometry is discussed and tolerances on the beam trajectory straightness are shown. The beam-based alignment algorithm and its application to correct the NISUS field errors are described.
