An electron-positron collider VEPP-4M is under operation now at BINP. The main goal of the present run is the precise measurement of mass of y -family resonances and t -lepton with the help of resonant depolarization technique. The status and recent results of the experiment are reviewed.

TNK facility (F.V. Lukin Institute, Zelenograd) was designed and manufactured at Budker INP. It includes 80 MeV electron linear accelerator-injector and two electron storage rings: the main ring for energy of 2.5 GeV and booster ring for energy of 450 MeV. The paper presents the functional layout of the linear accelerator. The disk-and-washer 2.8 GHz accelerating structure is described. Results of the accelerator startup is presented. In December 2005, accelerated electron current of ~50 mA with energy of ~50-60 MeV was obtained; the beam was captured into the booster ring.

Control system of Zelenograd Synchrotron Radiation facility, designed at the end 80-th last century, is in commission now. Old system was CAMAC based mainly. More advanced variant will consist in replacement of CAMAC modules with the embedded controllers. The report describes new hardware and software solutions.

The vacuum monitoring system of Kurchatov Center of Synchrotron Radiation is built on current measuring of sputter ion pumps mounted over vacuum chambers of accelerating units. Measuring hardware designed in INP SB RAS is using CAMAC standard and has been operating for a decade now. Hardware upgrade is accomplished by installing a PC workstation, connected through CAN bus to an in-house crate controller. Developed software comprises three levels. Firstly, there is a low-level program running inside the crate controller under RTX-166 operational system. Secondly, we have SQL Server database with client program, whose function is to create the queries at workstation side. And finally there are high-level applications running over network needed to display a current facility status and a data processing.

  A project of the new 2.5 GeV booster synchrotron to provide more effective injection of electron beam into Siberia-2, top-up injection, and for enhancement of light source performance, is developing in KCSR [1]. Existing 450 MeV storage ring Siberia-1 will be replaced by new synchrotron. The beam will be injected into the synchrotron at 80 MeV energy from the linear accelerator existed now. Top-up injection into Siberia-2 will permit to avoid the collective instabilities especially important during an injection, when insertion devices are using. In this report, the synchrotron parameters are presented, the basic systems are briefly described.
