Real-Time Redundancy for the 1.3 GHz Master Oscillator of the European-XFEL
Bartosz Gąsowski, Tomasz Owczarek, Krzysztof Czuba +2
Many modern large-scale facilities, like European X-ray Free Electron Laser (E-XFEL), require precise synchronisation, often down to femtosecond level. Even a very short interrupti…
Cavity Simulator for European Spallation Source
Maciej Grzegrzółka, Krzysztof Czuba, Mateusz Lipiński +1
European Spallation Source will be the brightest neutron source in the world. It is being built in Lund, Sweden. Over 120 superconducting cavities will be installed in the facility…
Additive phase-noise in frequency conversion in LLRF systems
Igor Rutkowski, Krzysztof Czuba
This contribution focuses on phase-noise added during frequency conversion in low-level radio frequency (LLRF) control systems. The stability of beams' parameters in linear acceler…
Phase Drift Compensating RF Link for Femtosecond Synchronization of E-XFEL
Dominik Sikora, Krzysztof Czuba, Pawel Jatczak +4
Modern high-energy particle accelerators and Free-Electron Lasers incorporate large quantities of sensitive RF and microwave frequency devices distributed over kilometer distances.…
