The National Synchrotron Light Source II is a third generation light source, which was constructed at Brookhaven National Laboratory. This project includes a highly-optimized 3 GeV electron storage ...ring, linac preinjector, and full-energy synchrotron injector. Budker Institute of Nuclear Physics built and delivered the booster for NSLS-II. The commissioning of the booster was successfully completed. This paper reviews fulfilled work by participants.

We report results of experiments performed with the KEDR detector at the VEPP-4M e^＋e^- collider. They include precise measurement of the D^0 and D^± meson masses, determination of the ψ（3770） ...resonance parameters, and a search for narrow resonances in e^＋e^- annihilation at center-of-mass energies between 1.85 and 3.1 GeV.
The results of synchrotron-radiation experiments, carried out at the VEPP-4M electron-positron collider in a wide energy range from 10 eV to 200 keV, are presented. To increase the radiation ...intensity, the electron-beam energy in the VEPP-4M accelerator ring is raised from 4 to 4.5 GeV. To carry out experiments in the high-energy range of synchrotron radiation, a new multipole hybrid wiggler, producing a field of 1.9 T, is installed at the accelerator ring. A method for calibrating the energy of electrons in the accelerator using a laser polarimeter is discussed.

We report results of a search for narrow resonances in e super(+e) super(-) annihilation at center-of-mass energies between 1.85 and 3.1 GeV performed with the KEDR detector at the VEPP-4M e ...super(+e) super(-) collider. The upper limit on the leptonic width of a narrow resonance inline image has been obtained (at 90% C.L.).

A method proposed to preserve the electron beam polarization at the VEPP-4M collider during acceleration with crossing the integer (imperfection) spin resonance at energy E=1763 MeV has been ...successfully applied. It is based on full decompensation of the \( 0.6\times3.3\) Tesla\(\times\)meter integral of the KEDR detector longitudinal magnetic field due to the anti-solenoids 'switched-off'.
The VEPP-4M accelerator facility with a universal KEDR detector is designed to conduct experiments with colliding electron-positron beams. High-energy physics, nuclear physics, and studies using ...synchrotron radiation are the main directions of research with this facility. In addition, experiments on poorly explored issues in the physics of beams in the electron-positron storage ring and methodological studies to prepare an experiment aimed at testing corollaries of the CPT theorem for an electron and a positron are regularly conducted at the VEPP-4 facility. A number of works performed in recent years are described: studies to increase the accuracy of comparing the electron and positron spin precession frequencies by the resonant depolarization method; measurements of the count rate of Touschek electrons as a function of the beam energy in a wide range; comparison of the methods for measuring the beam energy spread; a study of the electron beam dynamics when a nonlinear betatron resonance is crossed.
