	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.

	VEPP-5 Injection Complex (IC) supplies VEPP-2000 and VEPP-4 colliders at Budker Institute of Nuclear Physics (BINP, Russia) with high energy electron and positron beams. Since 2016 the IC has shown the ability to support operation of both colliders routinely with maximum positron storage rate of 1.7·10¹⁰ e+/s. Stable operation at the energy of 430 MeV has been reached. Research on further improvements on the IC performance is carried out. In particular control system was improved, additional beam diagnostics systems were developed, monitoring of RF system was upgraded. In this paper, the latest achieved IC performance, operational results and prospects are presented.

	This paper reports on the design features and con-struction progress of the barrier bucket RF systems for the NICA collider being built at JINR, Dubna. Each of two collider rings has three RF systems named RF1 to 3. RF1 is a barrier bucket system used for particles capturing and accumulation during injection, RF2 and 3 are resonant systems operating at 22nd and 66th harmonics of the revolution frequency and used for the 22 bunches formation. The RF systems are de-signed by Budker INP. Both RF1 stations were manu-factured, delivered to JINR and tested at the stand. The test results are presented in the article, as well as some results of calculating the effect of the RF1 system on the beam dynamics.
