	Funding: This work was supported by Russian Science Foundation (project N 14-50-00080). High-power free electron laser (FEL) facility NovoFEL has been created at Budker INP. Its wavelength can be tuned over a wide range in terahertz and infrared spectrum regions. As a source of electron bunches this FEL uses multi-turn energy recovery linac which has five straight sections. Three sections are used for three FELs which operate in different wavelength ranges (the first one - 90-240 microns, the second - 37-80 microns and the third - 5-20 microns). The first and the second FELs were commissioned in 2003 and 2009 respectively. They operate for users now. The third FEL is installed on forth accelerator track which is the last one and electron energy is maximal here. It comprises three undulator sections and 40 m optical cavity. The first lasing of this FEL was obtained in summer, 2015. The radiation wavelength was 9 microns and average power was about 100 watts. The designed power is 1 kilowatt at repetition rate 3.75 MHz. Radiation of third FEL has been delivered to user stations recently. The third FEL commissioning results as well as current status of the first and second FELs and future development prospects are presented.

	The total length of European X-ray Free-Electron Laser (XFEL) tunnels is 5,77 km. There are used about 300 corrector magnets for tuning electron beam. Every corrector magnet is fed by separate power supply. Power supplies for corrector magnets are distributed in 6 halls. So, replacing of one failed power supply produced too long pause in facility operations. The paper discussed different solutions which allow increasing reliability of corrector magnet power supply system for European XFEL.

THPSC020	Electromagnetic Compatibility of the Power Supply System for Corrector Magnets of the European XFEL	581
	O.V. Belikov, V.R. Kozak BINP SB RAS, Novosibirsk, Russia H.-J. Eckoldt, N. Heidbrook, B. Moelck DESY, Hamburg, Germany
	The power supply system for corrector magnets of European X-ray Free-Electron Laser (XFEL) includes more than 300 pieces the precise current sources. To avoid the influence each power supplies to others power supplies the developers should consider and provide the electromagnetic compatibility of power supply system components on the designing phase. For this purpose there should be limited electromagnetic emission from power supplies. There is necessity to provide the tolerance of power supplies against electromagnetic emission, electrostatic discharges and other interference from outside. The paper presents the structural solutions which allowed to provide electromagnetic compatibility and results of testing the developed power supplies.

	In 2016 the testing of the first section of the particle accelerator for the European X-ray Free-Electron Laser (XFEL) was completed and the results were excellent. BINP take anticipation in many works of XFEL construction. One of these works is developing, production, system assembling and putting in operation the power supply system for corrector magnets. Since 2012 there were developed, produced and delivered to XFEL 7 models of power supplies with up to 10 A output current and up to 70 V output voltage. Total quantity of delivered power supplies is near 400 pieces. The report presents the structure of power supply system and results of testing.

	E.V. Bykov, A.M. Batrakov, O.V. Belikov, Ye.A. Gusev, V.R. Kozak BINP SB RAS, Novosibirsk, Russia
	The system of beam correction for European XFEL includes about 400 precise current sources. Before including in XFEL equipment the every current source must tested and verified in concordance with specifications. For this purpose there was developed the automated system allowing to test up to 7 current sources simultaneously. The system consists of stand and software that written for linux OS. The stand was equipped by test loads, which emulated the real load, by precise DCCT and by precise analog-to-digital converters with CANbus interface. During testing the current in each current source was changed and digitized in concordance with different algorithms. The duration of typical session was 25 hours. The specific software was developed for this stand. It provides testing process, collecting and storing the primary information and displaying the first information. There are addition utilities which allows to make different analyzes in off-line mode using data accumulated during tests. The article provides a detailed description of the stand and main results.

THPSC078	Controller of Power Supplies for Corrector Magnets of European XFEL	715
	V.R. Kozak, O.V. Belikov BINP SB RAS, Novosibirsk, Russia
	The European XFEL is under construction now in Hamburg. It is a big international project. Budker Institute of Nuclear Physics (BINP) developed, produced and delivered power supplies for corrector magnets of XFEL. A controller for these power supplies was developed. It provides an 18 bits resolution of digital-to-analog converter and 6 channels of precise analog-to-digital converter with high accuracy and resolution. A combination of the general purpose functions with the specific function for power supplies allowed using the same controller for different equipment of corrector magnet subsystem. Here is described the controller, its properties and main applications.
