Power Supply System for Corrector Magnets of the European X-Ray Free-electron Laser

The total length of the European XFEL is 3.4 km. The electron beam parameters are corrected by about 300 corrector magnets, each powered by an individual power supply. BINP performed the development, production and delivery of the power supply system for the corrector magnets. For the powering of the corrector magnets, seven types of precision power supplies with output currents of up to 10 A and output voltages of up to 70 V were developed. To ensure high reliability of the power supply system BINP developed a “redundancy” system, which enables remote replacement of a faulty power supply with a spare one.
