[en] The first volume of proceedings of the 17-th Meeting on the charged particles accelerators (the Institute of High Energies Physics, Protvino, October 17-20, 2000) is presented. 93 reports, published in the first volume, were communicated in the following six sections: modern trends in developing accelerators, counter beams and particles storages, accelerating structures and power radiotechnique, control and diagnostic systems, high-intensity cyclic accelerators, superconducting magnets and cryogenic systems

[en] The second volume of the 17th Conference on the charged particle accelerators (Protvino, October 17-20, 2000) is presented. This volume contains 102 reports ,distributed by the following sections: magnetic systems and electric supply systems; particles dynamics in the accumulators and storage units; new acceleration methods; radiation problems in the accelerations; the accelerators reconstruction and development; the accelerators for medicine, national economy and applied purposes

[en] Increased requirements to the quality of forecasting the ionizing radiation fields resulted in improving the methodological and constant provision for the nuclear and radiation physical calculations, reflected in the new version of the RTS and T - RTS and T - 2000 software complex. The basic modifications, related to the new software complex, touch upon ways of describing the hadron and photoproduction processes in the range of intermediate energies and the geometry representation system. The synthetic scheme of geometry description, combining the possibilities of the combinatorial recursion method and the method of this second-order surfaces, is realized in this version

[en] The specialized power supply source (HF-300) for the electromagnets of the accelerator-storage complexes is developed. The IGBT moduli are used in the source as basic power elements. Besides, the HF-300 source is accomplished with application of the modern technology of the power high-frequency transformation, using the width-amplitude modulation signal. The source structural scheme, its realized parameters, structure and test results are described

[en] The report is devoted at developing the method for measuring the electrons energy, exterminated from technological linear accelerators. The possibility of applying the standard electromagnet-scanner for this purpose is experimentally shown. It is noted, that electrons measurement is carried out at any moment without the technological process interruption. The list of measurement operations and equipment, required for effective measuring the exterminated electrons beam, is presented

[en] The report contains brief review of the high-energy physics general state. On one side, development of the standard model provided for description of the Universe evolution on various stages of its development and explanation of this world. This fact may be considered as the theory triumph. On the other hand, a number of theoretical conclusions (the possibility of existing gravitons in the fifth dimension, formation of black holes by the heavy ions collisions and so on) testify to the fact, that origination of the crisis, which could open new prospects in studying the Universe, is possible. However, this crisis will not appear without new accelerators and maintenance of old ones

[en] The facility for precession stereotaxic radiotherapy with narrow photon Bremsstrahlung beams is described. The medical linear electron accelerator of the LUEhR-20M model is used as a Bremsstrahlung source. By the radiotherapy the accelerator operates in the mode of the Bremsstrahlung generation with the maximum energy of 18 MeV and the dose rate up to 56 Gy/min. Shaping of the Bremsstrahlung photon narrow beams is accomplished by a set of interchangeable collimators, having internal holes of the conic forms. The set consists of five collimators manufactured from tungsten-nickel alloy

[en] The purpose of this paper consists in clarifying the methodology for determining within the frames of the NRB-99 the radiation consequences during emergency effluents of gas tritium at the facility for studying the muon catalysis at the synchrocyclotron. Brief review of this facility is presented. It is shown that the required clarification may be accomplished in the case of determining the following values: the tritium gas permissible volume activity for the population, the tritium gas annual supply limit and dose coefficient

[en] The constant control of the beam capacity, electron energy and field size should be provided for a number of radiation technologic processes. The developed electron beam extraction system with energy of 6-10 MeV and capacity up to 10 kW, meeting these requirements consists of following components: the scanning magnet chamber, the scanning magnet with a power supply unit, mobile water-cooled current collector, ionization chamber, magnetoinduction sensor of beam current. Control of beam extraction and signal registration is carried out by the control system on the basis of micro-controller

[en] The MGTs-20 cyclotron of the Radium Institute are applied for production of medical radionuclides in six countries of the world during more than ten years. The paper contains data on production of radionuclides of iodine-123, gallium-67 and indium-111. The works on improving the RF-system, the ion source and the beam extraction system are described. The proposals aimed at modernization of the above cyclotron are also considered
