Digital Low Level RF for SESAME

Low Level Radio Frequency (LLRF) is an essential part of RF systems of synchrotron light sources. It is used to regulate the amplitude, phase, and resonant frequency of the RF cavities by using control loops. The requirement of highly stable and precise RF fields and better RF diagnostics leads to develop Digital Low Level Radio Frequency (DLLRF) for the synchrotron facilities. State of the art in digital technologies makes it possible to develop DLLRF for achieving required degree of stability of RF parameters. This paper will present the study of the DLLRF as well as the proposed strategy for developing the DLLRF for SESAME.
