	VEPP-2000 is the only electron-positron collider operating with round beams that allow to enhance beam-beam limit. VEPP-2000 with SND and CMD-3 detectors carried out two successful data-taking runs after new BINP injection complex was commissioned. The 2016/2017 run was dedicated to high energy range (640-1000 MeV per beam) while the 2017/2018 run was focused at 275-600 MeV/beam energies. With sufficient positron production rate and upgraded full-energy booster the collider luminosity was limited by beam-beam effects, namely flip-flop effect. Thorough machine tuning together with new ideas introduced to suppress flip-flop allowed to establish new world record for beam-beam parameter and bunch-by-bunch luminosity values at specific beam energies. The achieved luminosity increased 2-5 times in a whole energy range in comparison to phase-1 operation (2010-2013).

	VEPP-5 Injection Complex (IC) is designed to supply BINP RAS colliders with high energy electron and positron beams. Recently constructed K-500 beam transfer line connects IC to both VEPP-4M and VEPP-2000 colliders. IC two collider operation was successfully started in 2016. Nowadays, research on improvement of IC performance is carried out, in particular 10.94 MHz RF cavity was installed instead of 700 MHz one and a new 10 A electron gun installation is expected to be in winter 2018-2019. Moreover, streak-camera based longitudinal beam profile measurements in IC damping ring were carried out and BPM system in the damping ring was upgraded. Operation experience of IC and results of longitudinal beam profile measurements are reported.

	Damping storage ring (DR) is the part of VEPP-5 Injection Complex which provides electron and positron beams for BINP collider experiments since 2015. Basic lattice parameters of the ring (optical functions, dispersions, betatron frequencies, etc.) of the operating modes are presented in the article. Actual calculations of the ring aperture limitations and energy acceptance after RF-system reconstruction are given. Some instruments for the beam orbit control and magnet system adjustment were developed and can be applied to improve the productivity of beams generation.

WEPSB23	Development of a Generator of High-Voltage Nanosecond Squared Pulses Based on SOS-Diode and the High-Current Cold Cathode Thyratrons With Auxiliary Glow Discharge for Feeding of Inflectors IC VEPP-5
	S. Vasiliev, D.E. Berkaev, A.S. Kasaev BINP SB RAS, Novosibirsk, Russia
	An Injection Complex (IC) was designed in Budker Institute of Nuclear Physics in Novosibirsk in frame of a program of super high luminosity electron-positron facility VEPP-5. The stability of its operation is determined, among other things, by an injection-extraction system and, consequently, by generators of inflectors. For stable operation of the Injection Complex, these generators must produce pulses with maximum amplitudes of the output voltage of 50 kV and current in the load of the inflector 2 kA, the instability of the flat top less than 5% and its duration in the range from 20 to 92 ns; temporary stability of the generator should be ±2 ns and the output pulse's front ' less than 50 ns. In addition, it must be able to adjust the output voltage amplitude in the range of 10-100%. This paper presents the results of the design sample of a generator of high-voltage nanosecond square pulses based on SOS-diode and the high-current cold cathode thyratrons (pseudospark switches).
