  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.

Commissioning of e+/e− transfer line from Injection Complex to VEPP-2000 facility is done in 2016. Both electrons and positrons beams are injected to VEPP-2000 collider. The channel layout, lattice functions, magnetic elements, beam diagnostic system, vacuum system and control system are presented in this article. The details of commissioning process are also mentioned.

  The paper describes the bunch length measurement system for VEPP-2000 collider, equiped with optical analysers based on LI-602 dissector, which provides permanent measurements of the longitudinal beam profile. Potential well distorsion lengthening was measured at different bunch currents for the energies below 500 MeV. First measurements reveals the presence of microwave instabilty with turbulent emittance growth. The thresholds of these processes was used to estimate the values of reactive part of the longitudinal impedance. Measured energy loss factors was compared with computer simulations for the RF cavity. All results will be discussed and further estimations will be given.
