Power supply system for corrector magnets of the European X-Ray Free-Electron Laser
Total length of the European X-Ray Free-Electron Laser (European XFEL) tunnel is 3,4 km. There are used about 300 magnet correctors to justify position of electron beam. Each magnet is feed by separate power supply with high parameters. To have a stable beam the short time (up to 1 sec) deviation of output current should be less than 10^-5, long term stability should be better than10^-4. For this application the BINP SB RAS developed 7 types of power supplies with output current up to 10 A and output voltage up to 70 V. To provide high reliability of power supply system there was developed “hot replace” system allowing remote replacement failed power supply by reserved one. Now the power supply system is introducing in operation. The paper is reviewing details of power supply system for European XFEL.
