VEPP-4: status and prospects

Results of the VEPP-4 modification are presented, experiments conducted lately are enumerated, plans for further modification are described. Two ''snakes'' - 120 cm magnet with a flat sign-alternating field were installed in the VEPP-4, which permitted to suppress coherent instability. Power supply sources were modernized. Works to increase the luminoosity are conducted. In 1983-1984 the following experiment were carried out: precise mass measurements for γ' and γ''-mesons; measurement of lepton width of γ-meson; biphoton physics experiments. Spin dependence of synchrotron radiation intensity has been observed for the first time. On the basis of a laser polarimeter a source of the 800 MeV monochromatic γ-quanta is developed. Measures to increase the VEPP-4 luminousity by an order are enumerated. Modernization of the central part of the MD-1 detector is planned, as well as production of longitudinally polarized beams and interaction energy monochromatization
