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.

Electron-positron collider VEPP-2000 is under commissioning at Budker Institute of Nuclear Physics. The paper presents architecture, implementation and functionality of the software of the collider control system. The software according to hardware system consists of interacting subsystems responding on different acceleration facility parts. Control system software is based on several TCP/IP connected PC platforms working under operating system Linux and uses client-server techniques. The paper describes implementation, operating possibilities and perspectives of VEPP-2000 software. The paper also presents structure, architecture and implementation of the hardware of the collider control system. The system consists of pulse-elements, steering coils power supplies, high-current main field power supply, RF subsystems and some other special subsystems (such as vacuum, temperature, etc. control subsystems). The system is based on modern industrial protocol CAN-bus and specialized electronic BINP manufactured blocks according the standard. The paper describes implementation of different subsystems based on CANbus devices, and operating characteristics and possibilities.
