  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.

  The development of cyclic accelerators serves as a foundation in the field of synchrotron and neutron research, which is necessary for the creation of breakthrough technologies, as well as for the creation and development of research infrastructure. For this purpose, a synchrotron radiation source of generation 4+ is being created in Novosibirsk, SKIF. The main feature of this installation is an ultra-low emittance that allows you to provide a high beam brightness for research in various fields of science and technology. Important for SKIF is the availability of diagnostic tools that provide measurement of the transverse beam dimensions, which will help to minimize the emittance during setup and allow it to be compared with the calculated value of 75 pm * rad. The calculated emittance of 75 pm * rad corresponds to the vertical beam size of less than 8 microns at the radiation extraction sites. As part of the working project, a diagnostic complex was developed that includes a beam size monitor based on a double-slit interferometer. The monitor should provide interferometric measurements using σ-polarized SR both in the visible range and in the near ultraviolet, which will provide additional opportunities to verify the consistency of the results of beam size measurements.
