	To ensure self-amplified spontaneous emission process an undulator used for this must not deflect the electron beam from its orbit. The possible deflection of the electron beam, introduced by undulator, must be corrected by means of two air coils. These air coils, which are installed from both sides of the undulator, must eliminate not only the deflection angle, but also the displacement between electron beam trajectory and the orbit. For European XFEL 182 air coils are necessary. To minimize the measurement time an automated procedure has been developed and implemented. This paper describes the measurement setup, technical implementation method and automation procedure.

THPOPRPO22	Orbitkorrektur, a Java Client for Transverse Orbit Correction in PETRA-III	ion, optics, closed-orbit, alignment	120
	G.K. Sahoo, F. Brinker, F. Wedtstein DESY, Hamburg, Germany
	PETRA-III is a 3rd generation synchrotron light source dedicated to users at 14 beam lines with 30 instruments in the Max von Laue Hall and 10 beamlines in newly constructed Extensions in North and East which are under installations. PETRA-III is operated with several filling modes such as 60, 480 and 960 bunches with 100mA or 40 bunches with 90 mA at an electron beam energy of 6 GeV. Transverse orbits are corrected to a reference orbit, which is based on BBA measurements taking into account requirements of the beamlines and results of the dispersion correction. Histograms from 244 BPMs are displayed by means of this Java Client OrbitKorrektur. The orbits may be corrected using the Effective Correction Method with a few correctors or can be corrected using the SVD Method with proper singular Eigen values using theoretical response matrices from an Optic Server of used Optics. In this application additional features are implemented for better observation and analysis of orbits. Furthermore it can also be used to do many additional jobs, such as showing corrector set currents, loading golden and reference orbits, local bumps, displaying the first turn data during commissioning etc.

FRITPLCO04	Experience Gained during the Commissioning of the Undulator Control System at the European XFEL	ion, controls, MMI, FEL	148
	S. Karabekyan, S. Abeghyan, J. Pflüger, M. Yakopov XFEL. EU, Hamburg, Germany
	The European XFEL is a fourth-generation light source, which will start the operation in spring 2017. Three undulator systems - SASE 1, SASE 2 and SASE 3 - will be used to produce photon beams. For operation of all undulator systems, a total amount of 91 undulators have been produced and commissioned. SASE 1 and SASE 3 undulator systems, consisting of total 56 undulator cells, have been installed and prepared for the operation in the tunnel in spring and summer 2016. SASE 2 will be installed by the end of 2016. This paper describes the commissioning process of the whole undulator control system and reports about the experience gained over the entire duration of undulator control system commissioning.

The European XFEL is a fourth-generation light source, which will start the operation in spring 2017. Three undulator systems - SASE 1, SASE 2 and SASE 3 - will be used to produce photon beams. For operation of all undulator systems, a total amount of 91 undulators have been produced and commissioned. SASE 1 and SASE 3 undulator systems, consisting of total 56 undulator cells, have been installed and prepared for the operation in the tunnel in spring and summer 2016. SASE 2 will be installed by the end of 2016. This paper describes the commissioning process of the whole undulator control system and reports about the experience gained over the entire duration of undulator control system commissioning.
