This paper describes several beam instruments for VEPP-2000 complex. These beam instruments include: a secondary emission monitors and a image current monitors to measure beam position and tuning beam transport, installed into injection channels; a tuning measurement sys-tem to measure the beam tune; a DCCT measurement system to measure the beam DC current and beam life; a closed orbit measurement system and a transverse beam profile measurement system includes several button-type electromagnetic beam position monitors (BPM), optics, acquisition tools and high resolution CCD cameras distributed around the storage ring to measure the beam profile and its position. Some applications of these measurement systems and their measurement results are presented.

  VEPP-2000 collider magnet system consists from about 200 low-current corrections of magnetic fields which powered from independent power sources. During long-term operation of collider power sources ageing occurs. This ageing reveals in output current pulsation increasing with average statistical parameters maintaining. Standard power sources automation system does not allow discovering such malfunctions which may affect on collider operation stability. For the aims of discovering the pulsation special automation system was worked out. The system in oscillographic regime gets measurements of all channels of power sources one by one and carrying out spectral analysis determines malfunctions automatically. The paper describes technique and measurements results in details.

  The paper presents single-flight beam diagnostic system for VEPP-2000 injection channels. The system includes two types of beam position monitors: secondary emission monitor type and image current monitor type. Tuning of the system, calibration of monitors, hardware software of the diagnostic system are described. Main goal of the beam diagnostic system is tuning lossless beam transport. To solving such problem one need to tune up as guide fields as focusing fields of transportation channels. Thirst task ' trajectory correction ' is solving with response matrix inversion with SVD method. Second task ' optic function reconstruction ' is solving with help of multidimensional fitting of channel magnet structure parameters with minimization mean-square modeled response matrix from measured one. The paper presents results of practical methods for automated beam transfer and optic functions tuning for injection channels of VEPP-2000 complex.

  The paper presents architecture, implementation and functionality of injection channels control system for VEPP-2000 collider. The software according to hardware system consists of different interacting subsystems responding on different injection channels parts. The paper describes structure and implementation of the hardware of the collider control system. The system consists of pulse-elements; steering coils power supplies and nanosecond high-power inflectors (60 kV, 20 ns). The system is based on modern industrial protocol CAN-bus, CAMAC standard and specialized electronic BINP manufactured blocks according the standards. Software for the control system is based on several TCP/IP connected PC platforms working under operating system Linux and uses client-server techniques. CAN and CAMAC servers; different clients for control and power supply measurements; inflector control tools and their interaction with the rest of VEPP-2000 control system are described.
