VEPP-4M is an electron positron collider equipped with the universal KEDR detector for HEP experiments in the beam energy range from 1 GeV to 6 GeV. A unique feature of VEPP 4M is the high precision beam energy calibration by resonant polarization technique which allows conducting of interesting experiments despite the low luminosity of the collider. Recently we have started new luminosity acquisition run above 2 GeV. The hadron cross section was measured from 2.3 GeV to 3.5 GeV has been done. The luminosity run for gamma-gamma physics has been started. The luminosity at Y(1S) meson has been obtained. For the beam energy calibration the laser polarimeter is used. The paper discusses recent results from VEPP 4M collider.

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.
