The third generation synchrotron light facility Solaris will allow new research developments and innovation in disciplines like physics, chemistry, medicine and biology. The Polish National Syn- chrotron Radiation Centre — SOLARIS will be a unique facility in Poland [1]. The centre will be equipped with an electron storage ring and injec- tion system based on the technology developed at MAX-lab, Sweden [2, 3, 4].
In order to guarantee an overall lifetime of 13 hours (taking into account Touschek events) the partial pressure in the Solaris storage ring will be lower than 10−9 mbar. Synchrotron radiation from both bending magnets and insertion devices will be used. Bending magnet radiation will be taken from the centre of the first 15◦magnet of the double-bend achromat structure. The novel design of the small- bore achromat magnets from single iron blocks re- quires careful engineering of the vacuum chamber.
Most vacuum chambers will be made of stainless steel with different cross sections to match the vary- ing magnet gaps.
In this presentation a general description of vacuum system of both Solaris and the MAX IV 1.5 GeV storage rings, will be presented. The conceptual layout of the vacuum chambers in the
achromats and straight sections have been designed by the CELLS ALBA group (Figure 1). We will show the detailed design of vacuum chambers in- cluding the beam position monitors, discrete ab- sorbers and vacuum pumps.
