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.

The high voltage electron cooling system for the NICA collider is now under development in the Budker Institute of Nuclear Physics (Russia). The aim of the cooler is to increase ion beams intencity during accumulation and to decrease both longitudinal and transverse emmitances of colliding beams during experiment in order to increase luminosity. Status of its development and results of tests of the cooler elements are described in the article.
