AbstractAn important requirement for the European XFEL RF system is to assure a precise RF field stability within the accelerating cavities. The required amplitude and phase stability equals dA/A < 3E-5, dI <0.01 deg in the injector and dA/A <1E-4, dI <0.1 deg in the main LINAC at an RF frequency of 1.3GHz . To fulfil such requirements for the 3.4 km long facility is a very challenging task. Thousands of electronic and RF devices must be precisely phase synchronized by means of harmonic RF signals. We describe the proposed architecture of the RF Master Oscillator and the Phase Reference Distribution System designed to assure high precision and reliability. A system of RF cable based interferometers supported by femtosecond-stable optical links will be used to distribute RF reference signals with required short and long-term phase stability. We also present test results of prototype devices performed to validate our concept.
