BPM Based Optics Correction of the Solaris 1.5 GeV Storage Ring

The Solaris is a novel approach for the third generation synchrotron light sources. The machine consists of 600 MeV linear injector and 1.5 GeV storage ring based on 12 compact Double Bend Achromat (DBA) magnets designed in MAX-IV Laboratory in Sweden. After the commissioning phase of the Solaris storage ring the optimization phase has been started along with the commissioning of the first beamline. An essential part of the beam diagnostics and instrumentation system in the storage ring are Beam Position Monitors (BPMs) based on 36 quarter-wave button BPMs spread along the ring. Proper calibration allowed to measure and correct several beam parameters like closed orbit, tune, chromaticity, dispersion and orbit response matrix. The results of the latest machine optimization including the orbit correction, beam-based alignment and BPM phase advance will be presented.
