  The IHEP proton Accelerating and Storage Complex (UNK) includes in its first stage a 400 GeV conventional and a 3000 GeV superconducting ring placed in the same underground tunnel of 20.7 km circumference. The beam will be injected into UNK from the existing 70 GeV accelerator U-70. The experimental programme which is planned to start in 1995, will include 3000 GeV fixed target and 400-3000 GeV colliding beams physics. The size and complexity of the UNK dictate a distributed multiprocessor architecture of the control system. About 4000 of 8/16 bit controllers, directly attached to the UNK equipment will perform low level control and data acquisition tasks. The equipment controllers will be connected via the MIL-1553 field bus to VME based 32-bit front end computers. The TCP/IP network will interconnect front end computers in the UNK equipment buildings with UNIX workstations and servers in the Main Control Room. The report presents the general architecture and current status of the UNK control.

  An UNK Magnet Test Facility (MTF) is being constructed to provide cryogenic, electrical and magnet tests of superconducting (SC) magnets of UNK. The main parts of it are: The cryogenic system consisting in its turn of the central liquefier, ten satellite refrigerators, two compressors, purification system and transfer lines. The central liquefier supplies the satellite refrigerators with liquid helium. The liquefier is manufactured according to the scheme incorporating re-cooling by liquid nitrogen, two turbine expanders and a wet expander, - Four 8 kA, 24 V, ramped Power Supplies (PS) for cold testing of SC magnets, two 3 kA PS’s for instrumentation testing and calibration. Test facility in its turn consisting of: a) two dipoles and one quad benches for warm measurements; b) eight dipoles and two quad benches for cold measurements; c) two benches for instrumentation.
