Steps forward in the digital RF control system at LNS

The present radio frequency control system is changing under the influence of the new digital devices from the commercial broadcast industries. Since the introduction of the direct digital synthesized (DDS) as a new RF generator for the superconducting cyclotron in 2002, several measures aimed at improving the quality of the RF control system have been adopted in the digital field. Experimental results on RF digital prototypes of generators, turn-on, protections, phase and amplitude loops have been achieved. At the moment, a hybrid digital and analog RF control system is running at LNS. The status of these digital additions in the general frame of the present RF control system, will be given in this report.
