Phase Diversity Electro-optic Sampling: A new approach to single-shot terahertz waveform recording
Eléonore Roussel, Christophe Szwaj, Bernd Steffen +4
THz spectroscopy is an emerging tool for detection of microorganisms and harmful compounds in the food industry, the study of proteins in biomedicine and the development of electro…
Compact single-shot electro-optic detection system for THz pulses with femtosecond time resolution at MHz repetition rates
B. Steffen, Ch. Gerth, M. Caselle +8
Electro-optical detection has proven to be a valuable technique to study temporal profiles of THz pulses with pulse durations down to femtoseconds. As the Coulomb field around a re…
Real-time Data Acquisition and Processing System for MHz Repetition Rate Image Sensors
Aleksander Mielczarek, Dariusz Makowski, Andrzej Napieralski +2
One of the optimization goals of a particle accelerator is to reach the highest possible beam peak current. For that to happen the electron bunch propagating through the accelerato…
Electron beam profile imaging in the presence of coherent optical radiation effects
Christopher Behrens, Christopher Gerth, Gero Kube +3
High-brightness electron beams with low energy spread at existing and future x-ray free-electron lasers are affected by various collective beam self-interactions and microbunching…
Constraints on photon pulse duration from longitudinal electron beam diagnostics at a soft X-ray free-electron laser
C. Behrens, N. Gerasimova, Ch. Gerth +5
The successful operation of X-ray free-electron lasers (FELs), like the Linac Coherent Light Source or the Free-Electron Laser in Hamburg (FLASH), makes unprecedented research on m…
Generation and Characterization of Electron Bunches with Ramped Current Profiles in a Dual-Frequency Superconducting Linear Accelerator
P. Piot, C. Behrens, C. Gerth +5
We report on the successful experimental generation of electron bunches with ramped current profiles. The technique relies on impressing nonlinear correlations in the longitudinal…
First Observation of Self-Amplified Spontaneous Emission in a Free-Electron Laser at 109 nm Wavelength
J. Andruszkow
We present the first observation of Self-Amplified Spontaneous Emission (SASE) in a free-electron laser (FEL) in the Vacuum Ultraviolet regime at 109 nm wavelength (11 eV). The obs…
