Abstract

The phase and amplitude stabilization system of high-frequency voltage on the main cyclotron SSC of Heavy Ion Research Facility in Lanzhou (HIRFL) is introduced. The system composition, negative feedback loop design and other important aspects about the development of the system are particularly presented in this paper. Designing method of digital PLL orthogonal transformation and loop filter of phase and amplitude stabilization are introduced in detail. Control systems of SSC have been tested through a long-term stability experiments, the test method of the parasitic modulation suppression and stabilization in long term is proposed. According to the analyzing data, it shows that phase control accuracy in long term is within 0:014° and the amplitude deviation in long term is lower than 1.29x10^-4. Compared with the traditional system, its capability and target is much better.
