	Funding: This project was supported by the Ministry of Science and Education of Russia under contract No. 14.516.11.0084 Alternative nuclear energetic's technologies as fast reactors and accelerating driven systems (ADS) are necessary to solve a number of problems as U-238 or thorium fuel reactor and nuclear wastes transmutation. ADS subcritical system should consist of megawatt-power proton accelerator, neutron producing target and breeder. A number of ADS projects are under development in EU, Japan, USA, China, S.Korea at present. Superconducting linacs or their complexes with high energy storage synchrotron are under design in main projects as a megawatt power proton beam driver. In Russian Federation the complex design for accelerator-driver was carried down more than ten years ago. The new approach to the ADS complex is now under development in framework of the project carried out by collaboration between Russian scientific centers MEPhI, ITEP, Kurchatov Institute. This project was supported in 2013 by the Ministry of Science and Education of Russia. A brief results observation for accelerator part of the project is presented in report. It includes accelerator-driver general layout, beam dynamics simulation, electrodynamics simulations of accelerating cavities and analysis of technological background in Russia.

	Analytical calculations and numerical simulations have been done for mechanical eigenmodes of quarter wave superconducting resonators with operating frequency of 10⁶ MHz and 80 MHz. A possibility of frequency shift of mechanical modes in 106 MHz resonator has been estimated by application of the damper. We have optimized the damper's position for suppression efficiency. We have also compared the numerical and experimental results.

	Funding: Research supported by RFBR grant 13-02-00562/14 This paper is focused on HOM damping in 9-cell superconducting cavities. We are considering HOM propagation outside from the cavity ridged and fluted drift tubes. The analysis of the influence of the parameters of the drift tube on the HOM damping was conducted. The considered methods were analysed and compared.
