IHEP accelerating-storage complex (Present status and development)

The status of the UNK construction is described. The UNK parameters in the accelerating mode and parameters of colliding pp-beams are presented. The status of superconducting magnet development is shown. Seven ground technological buildings are being designed. The simulation of the first stage equipment is nearly completed. Vacuum systems, ring electromagnet power supply sources and injection channel magnets, first stage ring electromagnet, correcting magnets of the injection channel ring and lenses, are planned for production by the industry. The equipment models were tested in 1987 and in 1988 the serial production started. For tests of the UNK equipment the testing unit building occupying the area of 20 thousand m2 is constructed together with the corresponding test units. The construction and assembling works are planned to be completed by 1992
