Analog control loops for the Milan K800 cyclotron RF system

Technical Report:

Abstract

In this paper the desing criteria and the main features of the two analog feedback loops which are used to control the phase and the amplitude stability of the Milan Superconducting Cyclotron accelerating voltage are described, together with the resonator fine tuning system. The experimental results, obtained during the full power tests of the first RF cavity, are also presented. A phase stability better than {+-}0.2 grade centigrades and an amplitude modulation noise below 5{center_dot}10{sup -5} at 100 kV peak dee voltage were routinely achieved all over the frequency range (15/48 MHz).
