Abstract

VEPP-2000 collider magnet system consists of about 200 low-current corrections of magnetic fields which powered by 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. The standard power sources automation system does not allow discovering of such malfunctions which may affect on collider operation stability.

Special automation system was worked out for the aims of the pulsation discovering. In oscillographic regime the system e gets measurements of all power sources channels one by one and determines malfunctions automatically carrying out spectrum analysis. The paper describes this technique and measurements results in details.
