The Solaris storage ring represents a new class of light source that utilizes the innovative concept of a solid iron block containing all the Double Bend Achromat (DBA) magnets. The use of small magnet gaps brings the benefit of high fields but requires vacuum chambers of high me-chanical accuracy and distributed pumping. Due to very tight mechanical tolerances of the magnet blocks and of the vacuum vessels, the installation of the Solaris storage ring was a challenging task. In this paper the commission-ing results and the performance of this novel machine will be discussed.

  Solaris is a third generation light source recently constructed at the Jagiellonian University in Kraków, Poland. The machine was designed by the team at the MAX IV Laboratory. A replica of the 1.5 GeV MAX IV storage ring with a 96 m circumference was successfully built at Solaris and now the facility is in its 3rd phase of commissioning. The average pressure in the storage ring was 1.2·10-10 mbar before beam commissioning and increases to 1.2·10-8 mbar with 511 mA of stored beam current for electron energy of 524 MeV. With 10 A·h accumulated beam dose, beam cleaning has permitted an average pressure of 3·10-10 mbar/mA. In this paper the result of vacuum performance from beam cleaning and the beam lifetime will be presented. Moreover vacuum maintenance procedures will be reported.
