  VEPP-2000 is the only electron-positron collider operating with a round beam permitting to increase the limit of beam-beam effects. VEPP-2000 is the compact collider with 24.4 m-circumference which has record luminosity at energy up to 1 GeV per bunch (1032 1/cm2s), magnetic fields in superconducting solenoids (13 T) and in the bending magnets (2.4 T). Collider complex experimental program of 2019-2021 was focused on several energy ranges per bunch. Energy range in the second half of 2019 was 180-300 MeV, in the first half of 2020 ¿ 935-970 MeV, in the first half of 2021 - 970-1003.5 MeV. Data taking was carried out by CMD-3 and SND detectors and operation efficiency is compared with previous runs. Luminosity was limited by beam-beam effects. 2021 year was clouded by vacuum accident and subsequent intensive degassing using beam synchrotron radiation.

  Third-order resonance slow extraction from synchrotron is the most common use extraction method for external target experiments nuclear physics, proton and heavy ion therapy, since it can provide relatively stable beams in long time. The principle of third-order resonant slow extraction is intentionally exciting the third-order resonance by controlling detuning and sextupole strength to gradually release particles from inside to outside stable separatrix. BINP develop the ion synchrotron for wide range of technological application. The present paper describes slow extraction method with exiting betatron oscillations by the transverse RF-field. Such extraction technique provides stable current extraction for entire extraction time.
