Oral

Beam loading compensation is a key for acceleration of high intensity proton beams in the J-PARC synchrotrons, the rapid cycling synchrotron (RCS) and the main ring (MR). In both rings, magnetic alloy (MA) loaded rf cavities are employed to achieve very high accelerating voltages. The Q values of the MA cavities of the RCS and the MR are set to 2 and 22, respectively, so that the frequency...

16. Beam-Based Feedback for the European XFEL

Mr Sven Pfeiffer (DESY)

Oral

Pump-probe and seeding experiments at free-electron laser facilities such as the European XFEL are highly dependent on precise regulation of bunch arrival time and bunch compression. Combined RF field and beam-based measurement and feedback allow to fulfill these requirements. This contribution shows the beam-based feedback implementation for XFEL and current achievements and limitations at...
