  In this article some problems of optimizing the output beam of particles from the circular accelerator are discussed. In particular, we consider some problems of matching the booster, Nuclotron and collider in the NICA project. The main attention is paid to the matching of the extraction beam systems. The proposed approach allows providing qualitative and quantitative analysis of the impact of various factors of the corresponding control systems.

  The article considers the problem of forming a predetermined distribution density of the beam (in the phase or configuration space) in a periodic channel. The proposed approach is based on a method of constructing a beam mapping in the form of a truncated series consisting from matrices up to necessary order of nonlinearities. Similar approach allows us to formulate the given task as an optimization problem for some special functionals, created from parameters of the accelerator. Some results of the testing tasks are demonstrated.
