A digital LLRF control has been implemented at the CW linac ELBE at Helmholtz-Zentrum Dresden-Rossendorf. The system is based on the MicroTCA.4 standard and drives four superconducting TESLA cavities and two normal conducting buncher cavities. The system enables a higher flexibility of the field control, improved diagnostics and field stability compared to the analogue system which was used...

Oral presentation
A fast and robust closed orbit feedback (COFB) system is realized at SIS18 synchrotron of GSI for the orbit correction during the acceleration cycles. ORM variation over the fast ramps due to the triplet-to-doublet quadrupole transition from injection to extraction posed a unique challenge for the stability of the feedback system. The theoretical investigations are presented made using control...

The Accelerator Research Experiment at SINBAD (ARES) is a conventional S-band linear accelerator which will be capable of producing ultra-short electron bunches with duration of a few femtoseconds and energy of up to 100 MeV. The SINBAD injector laser synchronization has recently been extended with with an advanced laser-to-RF phase detector, which is based on an integrated Mach-Zenhnder...

The carrier suppression method offers a leap in terms of measured amplitude and phase resolution compared to other methods. The method allows overcoming the ADC noise barrier which can give resolution improvements of 30 dB compared to other methods. Our current work includes mostly finding the best technologies of various building blocks which should ultimately lead to a viable testing of a...

The design of a beam-based feedback control for the superconducting electron linear accelerator ELBE is progressing through its modelling stage. By taking into account the continuous-wave mode of this accelerator with its inherent steady-state RF operation we propose a disturbance rejection control scheme that takes the process disturbance explicitly into account. In particular, we analyze the...

The optical synchronization system for European XFEL provides few femtosecond ultra-stable timing synchronization for accelerator subsystems and experiments. It will be the first accelerator subsystem at EuXFEL to receive an extensive data acquisition system to capture all status and operation relevant system parameters available in the DOOCS control system for uninterrupted multi-year time...

At the Ferninfrarot Linac und Test-Experiment (FLUTE) a regular operation with electron beam in the first section, up to 7 MeV, was achieved. For time resolved experiments the accelerating field amplitude and phase in the RF gun needs to be stable to better than 0.1%. At FLUTE a high influence of the 50 Hz AC-line power was observed and investigated. Utilizing the MRF timing distribution and...
