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 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.
