  VEPP-2000 is electron-positron collider exploiting the novel concept of round colliding beams. After three seasons of data taking in the whole energy range of 160-1000 MeV per beam it was stopped in 2013 for injection chain upgrade. The linking to the new BINP source of intensive beams together with booster synchrotron modernization provides the drastic luminosity gain at top energy of VEPP-2000. Recomissioning status, fist results and perspectives of the VEPP-2000 complex will be presented.

  VEPP-4 and VEPP-2000 e+e− colliders are switching to feed from VEPP-5 Injection Complex via newly constructed K-500 beam transfer line. Since first operation of K-500 at the end of 2015 injection complex delivered e+ and e- beams to VEPP-2000 facility and is getting ready to work with VEPP-4. Upgraded injection chain demonstrated ability to provide design luminosity toVEPP-2000 and techniques of reliable operation are now under development. The designand operation experience of Injection Complex and transfer lines will be presented.

  In November 2013, the FAIR management delegated the responsibility for the technical design, construction, installation, and commissioning of the whole CR and its components from GSI to Budker Institute of Nuclear Physics (BINP). Since that time a lot of modifications of the original design were made aiming to improve the beam parameters and the machine performance. This work shows the present status of the development.

  In the end of 2015 the Injection Complex VEPP-5 was turned into operation in the Budker Institute of Nuclear Physics (Novosibirsk, Russia). The main purpose of the VEPP-5 facility is supply the BINP colliders VEPP-2000 and VEPP-4 with high intense beams of electrons and positrons. At the VEPP200 synchrotron buster BEP is used as collector ring for electron or positron beams which supplied by VEPP-5. A generator of a pair of negative and positive polarity pulses bases on two double pulse forming network with hydrogen thyratrons was used for injection and extraction into BEP. The rise and fall time of this pulse have a typical time is 85 ns, and the period of revolution electron and positron beams in BEP is 70 ns. The pulses with rise/fall time no more 20ns and flat top not less 20 ns is necessary to provide for a new scheme of injection. The concept of the power supply for such kicker system is presented in the paper.

  The FAIR project is an accelerator facility of the next generation. By the contract of responsibility BINP develops the Collector Ring - part of FAIR. Kicker system will be used for injection and extraction system of the ring. The six ferrite kickers are installed inside of the two vacuum chambers. Specific power supply with the ability to change the duration and polarity of pulses is needed. In this article the concept of kicker system and power supply for it is described.
