  In current work a task of modelling of dynamic of charged particles in RFQ structures in BDO RFQ program complex is considered. Following models are realized in program complex: dynamic model of particles in equivalent running wave, dynamic model of particles in the envelops and model of 3D dynamic in standing wave. Parameters export between the models is carried out. For Coulomb interaction of charged particles different models of method of large particles are carried out as well as methods based on analytic approach of Coulomb field of the beam and estimation of the Coulomb field by net method. A possibility of results comparison with Coulomb field of particles by different methods is foreseen in this program complex. User graphic interface allows to choose a model, to enter and modify the parameters, to review calculation results.

  Program complex for modelling of transverse dynamic of particle beams and orbit correction at Nuclotron synchrotron (LHEP JINR) is considered in current work. The program complex provides calculation of transverse dynamic of charged particle beams in Nuclotron and its axis, based on linear model with transport matrix of lattice elements, calculation of Nuclotron Twiss parameters, acceptance and emittance of the beam. A possibility to optimize the location of beam position monitors (pick-up) and multipole correctors is foreseen as well as calculation of the orbit with measuring data of pick-up stations of Nuclotron. Program complex includes realizations of orbit correction algorithms with response matrix and provides correction of the orbit in Nuclotron. User's graphic interface provides interaction of user with program complex, including performance on demand of the user of separate functions of the program complex, providing input and maintenance of parameters, download from file and record into the file of parameters and calculation results, graphical view of the calculations results in program complex. Program software environment is integrated with MAD-X program (upload, processing of data to and from, visualization). Format of input and output data is compatible with relevant MAD-X format.
