	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.

WEPSB059	Realization of Positron Annihilation Spectroscopy at LEPTA Facility	electron, detector, ion, radiation	496

	Positrons are used in materials science to study open volume defects. Several positron annihilation spectroscopy (PAS) techniques exist. These methods are based on detection of the 511 keV gamma quantum. The first method is the analysis of the Doppler broadening of annihilation line and provide information about defect concentration. Both annihilation quanta can be observed. Coincidence observation of two quanta gives additional information about the environment around defect. The second method is based on lifetime concept, which allows to distinguish type of defects. Nowadays, positron beams are of great interest for materials science. Using a low energy, monoenergetic beam it is possible to control the positron penetration depth from the sample surface to a depth of several microns. Thus, the beam can be used to characterize thin films, analysis of surface modification, studying influence of ions on matter etc. This report aims to present a current status of realization and progress in PAS methods at LEPTA facility at JINR.

	The report aims to present the status of the development of the LEPTA facility for further enhancement of the positron annihilation spectroscopy (PAS) method application at the LEPTA facility. The research in solid state physics performed currently is based on slow monochromatic positron flux from the injector and Doppler PAS. The new positron transfer channel being under construction at the LEPTA allows us to develop more advanced PAS method - so called 'Positron Annihilation life-time spectroscopy' (PALS). It will enrich significantly the research program at the LEPTA. PAS method is sensitive to microdefects in solids. A pair of gamma quanta, born as a result of positron-electron annihilation carries information about the density of the defects that have the size less than 10 nm and are located at the depth from the surface of the material depending on the positron energy. New monochromatic positron source construction supplied with the autonomous cooling system with emitter-source of the activity of 30 mCi (iThemba LABS production) and new positron transfer channel are presented in report.
