Solaris is a third generation light source operating since 2015 in Krakow, Poland. Between 2015 and 2018 the synchrotron as well as two beamlines were commissioned. During the commissioning phases the good performance of Solaris storage ring was reached. The beam optics was brought close to the design one. Since October 2018 the Solaris storage ring is in the user operation mode. Moreover, two other beamlines (PHELIX and XMCD) with elliptically polarized undulators used as source have been installed, currently under commissioning. In 2019 the total beam availability of $91.9\%$ was reached with the average circulating current of 280 mA and the total lifetime of 25 h. Over the last year few improvements of the storage ring were done in order to optimize the storage ring performance. The Landau cavities were tuned to improve the Touschek lifetime and to suppress the instabilities. Two diagnostic beamlines were set up and commissioned, allowing for the beam size and the emittance measurements. The storage ring optics was fine-tuned to increase the dynamic aperture.

Solaris是自2015年以来在波兰克拉科夫运营的第三代光源。在2015年至2018年之间，同步加速器以及两条光束线已投入使用。在调试阶段，达到了Solaris存储环的良好性能。光束光学系统已接近设计。自2018年10月以来，Solaris存储环处于用户操作模式。此外，还安装了另外两条带有椭圆偏振起伏器作为光源的光束线（PHELIX和XMCD），目前正在调试中。2019年的总光束可用性$91.9％$达到280 mA的平均循环电流和25小时的总寿命。在过去的一年中，为了优化存储环的性能，几乎没有对存储环进行任何改进。对Landau腔进行了调整，以改善Touschek的寿命并抑制不稳定性。设置并调试了两条诊断光束线，可以进行光束尺寸和发射率测量。微调了存储环光学器件，以增加动态光圈。
