Bending magnets for the metrology light source (PTB, BERLIN)

Eight bending magnets for Metrology Light Source (PTB, Berlin) were manufactured by Budker INP, Novosibirsk, Russia. MLS operate within wide electron energy range (200 – 600 MeV), which corresponds to 0.43 T - 1.31 T for the bending magnets. The laminated C-shape dipoles have the bending radius of 1.528 m (bending angle of 45 deg.) and parallel edges. The bending magnets were magnetically measured by Hall probe system designed in Budker INP and the magnetic field homogeneity inside the working area was ± 2.5.10-4. The main features of mag- netic modeling, manufacture and magnetic measurements are presented in the paper. The meas- ured basic parameters of the manufactured bending magnets have good agreement with the model simulation.

Tens kilowatt power supply based on half-bridge inverter with zero current commutation

The 40 kW power supply prototype based on half-bridge inverter with zero current commutation has been developed. The power supply is to be used for VEPP-5 modulators pulse forming net- works charge up to 45 kV with repetition rate up to 50 Hz. The inverter operation algorithm pro- vides IGBT switching with zero current condition. The power supply test results are presented. The design of the step-up power transformer operating at frequency up to 30 kHz is described.
