  The 2 MeV electron cooling system at COSY-Jülich started operation in 2013. The cooling process was observed in the wide energy range of the electron beam from 100 keV to 1.26 MeV. Vertical, horizontal and longitudinal cooling was obtained with bunched and coasting proton beam. This report deals with electron cooling experiments at COSY with proton beam at energy 1.66 and 2.3 GeV. The proton beam was cooled at different regimes: RF on and off, barrier bucket RF, and cluster target on and off.

  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.
