Description
Solaris – the first Polish synchrotron light source built in Krakow is in operation since mid-2015. The storage ring is a twin brother of MAXIV 1.5 GeV storage ring installed in Lund, Sweden. The lattice is composed of double bend achromat (DBA) cells with zero-dispersion straights and exhibits 12-fold symmetry. With the circumference of 96 m and energy of 1.5 GeV, its strong focusing and ultra-compact lattice enables to reach the natural emittance of 5.98 nm-rad. It also provides twelve 3.5 m long straight sections and ten of them can host the insertion devices (IDs). The injection septum and diagnostics is located in the 1st straight section (SS) whereas the RF cavities occupy the 12th SS. In the 3rd SS the injection dipole kicker is installed, therefore in this location only short (up to maximum 1.6 m) ID can be installed. Performance of position monitoring devices has proven essential for the successful 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 reducing 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 storage ring and the commissioning results will be reported.
