摘要：
Recent work has been undertaken to renew the stabilization system for the beam energy at the Bucharest Tandem Accelerator. In the present paper the mechatronic design of the new system is presented and the running consistency of the new electronic circuits is shown. The experimental tests have shown that the new system has improved the quality of the accelerated beams in terms of stability and energy resolution, especially at lower accelerating voltages. As a result of the present development we show an improvement with 20% for the peak to peak medium value of the high voltage ripple on the terminal. This improvement also allowed to lower the minimum stable voltage on the terminal from 1.5 MV to 0.8 MV. (C) 2012 Elsevier B.V. All rights reserved.
