Description

The redesigned RF reference generation and distribution system at FLASH was installed in 2022. The upgrade is based on a European-XFEL-based Main Oscillator (FL-MO1300), Frequency Conversion (FL-FCM), and RF Distribution (FL-DISM) modules. The main 1.3 GHz RF reference signal is synthesized in FL-MO1300, and the remaining signal frequencies are synthesized in FL-FCM and synchronized to the main 1.3 GHz reference. All reference signals are distributed via the FL-DISM. All the modules provide live monitoring of most RF signals and diagnostic information via the DESY DOOCS system. The contribution presents the recent operation experience of the upgraded RF reference system at FLASH, including long-term logged parameters, like main oscillator stability, distribution output power level, and the system modules’ temperature stability.
