  The Kurchatov synchrotron light source operates in the range of synchrotron radiation from VUV up to hard X-ray. To improve facility capabilities in the last few years technical modernization of all facility systems is underway and new beam lines are constructed. In this report the present status and future plans of the Kurchatov synchrotron light source is presented.

The nonlinear effects are very important in the development of new accelerators and synchrotron light sources. Nowadays they are one of the main factors limiting the achievement of the required facility parameters. In many cases in the development of new accelerators the analytical estimations give very coarse results and in some cases they don't apply at all. Therefore, the best way to research and design accelerators is to use numerical simulation. Nevertheless, very often during complex physical process simulation (taking into account many nonlinear effects) the use of classical optimization methods is difficult and does not give the desired results. The article deals with the application of multi-objective optimization using genetic algorithms for accelerators and light sources. These algorithms allow both simple linear and complex nonlinear accelerator structures to be optimized with the same effectiveness to achieve the required facility parameters.

Coherent instabilities of the bunched beam are one of the reasons that limit a total beam current in the storage rings. Although there are solutions of this problem, the estimation and reduction of wake-fields influence on the longitudinal beam dynamics remain important things. In the article we return to the subject of coherent instabilities of the unevenly-filled bunches in the storage rings.
