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 magnetic modeling, manufacture and magnetic measurements are presented in the paper. The measured basic parameters of the manufactured bending magnets have good agreement with the model simulation.

The Metrology Light Source (MLS), a specialized synchrotron radiation source (electron energy up to 600 MeV) being built at the PTB in Germany. The multipole magnets of the Storage Ring consist of 24 quadrupoles, 24 sextupoles and 4 octupoles manufactured by Budker INP. The quadrupole magnets of 165 mm length have gradient of 13 T/m and aperture of 70 mm. The sextupole magnets of 80 mm length have strength of 280 T/m2 and aperture of 76 mm. The octupole magnets of 80 mm length have strength of 2400 T/m3 and aperture of 86 mm. The main features of magnetic modeling and manufacture are described in the paper. The multipoles were magnetically measured by Rotating Coil System and main results of the magnetic measurements are also presented.
