Hardware and Software Package for Fine Adjustment of the PETRA-III Damping Wigglers

At the end of 2009, an extremely low horizontal emittance of 1 nm rad was achieved at the PETRA-III storage ring (Hamburg), a new third-generation SR source with an energy of 6 GeV, which offers new opportunities for SR experiments. Such an emittance was achieved through the efficient operation of a 4-m permanent magnet, with damping wigglers installed in long straight sections of the ring. The required final magnetic characteristics of the wigglers were achieved using the hardware and software package developed at the Budker Institute of Nuclear Physics (Novosibirsk). This paper briefly describes the magnetic measuring techniques, the equipment used and their parameters. A special section is devoted to the description of the programs for equipment control, data processing and presenting.
