Work on the conceptual design of a dedicated fourth-generation fourth-generation Specialized Synchrotron Radiation Source (SSRS-4) is in progress at the Kurchatov Institute, Moscow. The project is being developed in collaboration with the European Synchrotron Radiation Facility (ESRF) in Grenoble, France. In this paper, the initial results of our work on this project are reported, major directions of current research are presented, and possible areas of application of the SSRS-4 are outlined. The key element of the currently discussed design is a 6-GeV storage synchrotron with an orbit length of ~1300 m and the magnetic lattice that should provide a horizontal transverse emission of 70–100 pm rad. Further optimization may allow for reducing the emittance to 20–40 pm rad. Of the injection schemes under discussion, one features a full-scale booster synchrotron deployed in the same tunnel as the main storage ring, and the second is a topup linac. The latter can also be used as an electron-beam driver for a free-electron laser.

INTRODUCTION The effectiveness of the design on the stage of computer simulation is largely determined by the convenience of the user interface of the used software package and the time of adaptation of the user to that application [1-4]. This paper presents a new approach in the implementation of interface software package KATRAN, designed for the design of channels of transportation of a relativistic charged particle beams. THE PACKAGE STRUCTURE AND ALGORITHM DESIGN The package contains four main modules: graphical interface, consisting of the Builder module of the channel and the processing module results of the calculation; calculation module; database module.

The recent results of the work carried out by the laboratory of charged particle accelerators information systems in Department of Electrophysical facilities NRNU MEPhI are considered. The researches are connected with the creation of the data-processing support center and remote access of the main educational cycles (within the department). The creation process of the virtual electrophysics laboratories, which can simulate the operation of the main accelerators subsystems and the related research work, is also considered..
The paper discusses the method of designing channels based on numerical simulations with the aim of achieving optimal beam parameters at the exit of the channel. Methodology was used to optimize the parameters of the transport channel of the electron accelerator, with significant loss of beam intensity in the output beam from the accelerator and in the process of transport of the beam for the experimental equipment.
This paper contains results of numerical simulation of the existing transportation channel synchrotron "Pakhra" having a significant loss in the intensity of the electron beam in the device output beam from the accelerator and beam transport process in a experimental installation. The main objective of the study is to increase the beam intensity by optimizing the channel structure and parameters of its elements.
The authors present method of calculation of optimal parameters of the magneto-optical systems using extreme methods of searching. Particle dynamics in transportation channel is described by the matrix formalism using programming system MATLAB. The calculation consists of two stages: preselection of quadrupole lenses and focusing system geometry; determine of optimal system parameters by Nelder-Mead method.
Output devices and charged particles transport channels are necessary components of any modern particle accelerator. They differ both in sizes and in terms of focusing elements depending on particle accelerator type and its destination. A package of transport line designing codes for magnet optical channels in MATLAB environment is presented in this report. Charged particles dynamics in a focusing channel can be studied easily by means of the matrix technique. MATLAB usage is convenient because its information objects are matrixes. MATLAB allows the use the modular principle to build the software package. Program blocks are small in size and easy to use. They can be executed separately or commonly. A set of codes has a user-friendly interface. Transport channel construction consists of focusing lenses (doublets and triplets). The main of the magneto-optical channel parameters are total length and lens position and parameters of the output beam in the phase space (channel acceptance, beam emittance beam transverse dimensions, particles divergence and image stigmaticity). Choice of the channel operation parameters is based on the conditions for satisfying mutually competing demands. And therefore the channel parameters calculation is carried out by using the search engine optimization techniques.
The authors present a complex of computer laboratories that simulates major subsystems of electrophysical facilities. Lab software interface creates a research environment with diverse electrophysical equipment, including assembly of the experimental circuits, setting their parameters and characteristics, starting and carrying out the necessary research. Models of subsystems are based on both mathematical modeling and use of tabular experimental data as well as features of real devices.
The authors consider problems of interaction of high energy particles with electromagnetic fields. Solution of many problems in accelerator technology are formulated in a matrix form, and therefore the use of MATLAB is the most effective. Range of such tasks is quite wide - from particle dynamics in individual elements of accelerator technology to the design of multi-elements transportation channels, where optimal parameters are determined by using extreme methods of searching.
The work is devoted to the questions of creation at the Department of Electrophysical Installations of a center of information support for the main education cycles connected mainly with solving the problems of electrophysics. An important part of this development is to guarantee the safety and integrity of rapidly changing information resources of the center. The peculiarities of the information systems of computer education centers make their specific demands to the necessary protection of the information resources from accidental and intentional factors, especially in connection with development of remote education.
