	Preliminary results on accelerating cavities for USSR-4 facility (also known as SYLA - SYnchrotron and free-electron LAser) project are presented. This facility is under development by collaboration hosted by National Research Center "Kurchatov Institute". SYLA is synchro-tron radiation facility based on injector linac and 6 GeV storage ring. Beam energy loss in storage ring is to be compensated by several modified pillbox cavities. Cavity geometry features, its operation frequency choice and induced HOM parameters are discussed. HOM damping technique using corrugated cylindrical waveguides were studied. Longitudinal impedance values of HOM are presented for initial accelerating cavity and structure with waveguides.

	Beam parameters control and operation software tools for BINP VEPP-5 Injection Complex Damping ring consisting of two parts were developed. Beam parameters control includes processing of measured turn-by-turn beam coordinates from all Damping ring beam position monitors and displaying such features as tunes and beam position into vacuum chamber. This part gives an opportunity to measure Damping ring response matrices and carry out its processing too. Beam parameters operation is based on knobs creating. Knob is combination of accelerator control elements, which performs an isolated shift of one selected parameter, e.g. only vertical betatron tune. This part is devoted to their creation and application on Injection Complex VEPP-5. This paper presents review of developed software tools and their application result on VEPP-5 Injection Complex: beam position adjustment via response matrix measurements and quantification the amount of Damping ring captured particles during the injection process depending on beam tunes.
