  After one year of the Solaris storage ring commission-ing excellent performance has been achieved. The optics was corrected close to the design values. However, some minor adjustments are still needed. The commissioning of the Solaris 1.5 GeV storage ring required a big effort in machine parameters optimization. Performance of posi-tion monitoring devices has proven essential for the suc-cessful optimization of beam parameters such as: closed orbit, tune, chromaticity, and dispersion. Now, the effort is focused on fine-tuning the machine by implementing the linear optics from orbit correction (LOCO) and reduc-ing the disparity between model and measured results revealed by the phase advance analysis and dispersion measurement. Moreover, during daily operation the main task is to maintain long-term stability of the circulating electron beam allowing for beamlines commissioning. Within this presentation the current status of the Solaris facility and the commissioning results will be reported.

  Solaris storage ring is a recently constructed and commissioned machine. At the beginning of storage ring operation the lifetime was very short mostly dominated by the ion trapping and residual gas scattering. After a 390 A·h of beam cleaning the measured total lifetime has reached 20 h for 100mA of a stored current. Since the main contribution to the total lifetime in the storage ring comes from single Coulomb and Touschek scattering the dependence of the residual gas pressure and the vertical aperture of storage ring is investigated. Moreover to improve the Touschek lifetime the 3rd harmonic cavities were installed. Recently the cavities were tuned close to the resonance and the total lifetime increased significantly. This presentation will report on the lifetime measurements and calculations carried out for Solaris 1.5 GeV storage ring at different vacuum and RF conditions.

  Solaris is a third generation light source constructed at the Jagiellonian University in Kraków, Poland. The machine was designed by the MAX IV Laboratory team. The replica of the 1.5 GeV storage ring with 96 m circumference of a vacuum system was successfully built and now the synchrotron facility is after the 3rd phase of commissioning. Recent installation of the Residual Gas Analyzer (RGA) in the storage ring allows now for evaluation of the residual gas composition. Within this paper the result of residual gas analysis in the vacuum system of storage ring during different states of the machine will be presented. Result of vacuum performance regarding beam cleaning and beam lifetime will be presented. Moreover, the NEG strips performance will be evaluated and reported.
