Popis: VEPP-2000 electron-positron collider operating in the beam energy range of 150-1000 MeV is the only machine originally designed for and successfully exploiting Round Beams Concept. After injection chain upgrade including link to the new BINP injection complex VEPP-2000 proceeded with data taking since 2017 with luminosity limited only by beam-beam effects. At the low energies (300-600 MeV/beam) the novel technique of effective emittance controlled increase by weak coherent beam shaking allowed to suppress the limiting flip-flop effect and resulted in additional luminosity gain factor of 4. The averaged delivered luminosity at the omega-meson production energy (2*391 MeV) achieved L = 2*10³¹cm⁻²s⁻¹/IP. At the top energies above nucleon-antinucleon production threshold the stable operation with luminosity of L = 5*10³¹cm⁻²s⁻¹/IP resulted in high average data taking rate of 2 pb⁻¹/day in 2020.
