Electron diagnostics, timing, synchronization & controls: Session-10
- Rasmus Ischebeck (Paul Scherrer Institut)
Time-resolved diagnostics with sub-femtosecond resolution are of crucial importance for ultra-fast x-ray FEL applications. Radio-frequency (RF) transverse deflector structures (TDS) are typically employed to characterize the temporal properties of the electron beams driving FELs. If located after the undulator section, the TDS can measure the FEL power profile as well. In this contribution, we...
Enhancing the performance and capabilities of free electron lasers, such as LCLS-II, hinges on our ability to precisely control and measure the 6-dimensional phase space distribution of the beam. However, conventional diagnostic techniques necessitate a substantial number of measurements and computational resources to characterize a single beam distribution, using many hours of valuable beam...
To satisfy recent complex requirements from XFEL applications, an automated tuning tool has been developed and regularly used for daily XFEL operations at SACLA. In a ring-based synchrotron radiation facility, an electron beam with identical characteristics is provided to many user beamlines. In contrast, in a linear accelerator-based XFEL facility with multiple beamlines, the electron beams...
Ultra-fast science at free electron laser (FEL) facilities is pushing accelerator and FEL technology towards shorter laser pump and FEL probe pulses to resolve fast dynamics.
Ideally, the short pulses should be backed by a synchronization system that provide a pump-probe jitter that is similar to the pulse duration. This is challenging, and the achieved timing jitter is typically one order...
Laser-based electro-optic detection is a well-known tool for characterizing electron bunch shapes - and electric fields in general – in single-shot. However, reaching sub-ps resolution together with long acquisition length still remains a challenging problem. This motivated a search for novel conceptual approaches to the problem, based on the so-called diversity schemes* (i.e., using multiple...
