Description
Time to visit the posters and discuss specific topics with the experts.
Posters will be accessible throughout the whole event, in the hallway of Bldg.3, ground floor.
Please view the list of contributions in this session for details on the presented topics.
A high-power, tunable terahertz (THz) source based on an accelerator is currently under development at the Photo Injector Test facility at DESY in Zeuthen (PITZ) to support pump-probe experiments at the European XFEL Recent progress includes the successful demonstration of a single-pass THz free-electron laser (THz FEL), generating pulse energies exceeding 100 μJ at a central frequency of...
The future circular electron-positron collider (FCC-ee)
is designed for highest luminosity to enhance the precision
of high-energy particle physics experiments, spanning en-
ergies from the Z pole to the t$\bar{\text{t}}$ threshold. As outlined in
its conceptual design report, high-precision measurements
of the longitudinal bunch profile are required across mul-
tiple operation modes,...
Our projects aim to enable cost-effective diagnostics and improved performance in next-generation research facilities. This poster presents the development of a high-speed digitizer for capture of fast transient signals and customized vacuum feedthroughs enabling reliable transmission of high-bandwidth data across vacuum barriers.
The FLASH1 THz beamline at DESY produces intense multicycle THz undulator radiation along with quasi-single-cycle edge radiation. Precise characterization of such FEL-based THz pulses is hindered by the inherent timing jitter between the THz pulse and external lasers synchronized to the FEL master clock. While Electro-Optic Sampling (EOS) is a powerful diagnostic technique, this timing jitter...
We will give an overview of the Smith-Purcell and Transition Radiation based longitudinal diagnostic methods employed at the ARES (Accelerator Research Experiment at SINBAD) linear accelerator to characterise femtosecond long electron bunches.
Detailed phase space reconstruction of electron bunches is essential for optimal free-electron laser performance. Conventional techniques become increasingly inefficient for full six-dimensional phase space reconstruction. This project explores the use of Generative Phase Space Reconstruction (GPSR) technique to reconstruct the full 6D phase space of electrons at the FLASH2 beamline from 2D...
Coherent THz radiation has become an important type of electromagnetic radiation in many fields of basic and applied studies of matter. It also serves as a valuable diagnostic of longitudinal bunch characteristics in electron accelerators. Electro-optic methods enable direct measurement of the THz field. In the customary method of electro-optic sampling (EOS), it is necessary to make many...
Operating high-gain FELs with ultra-low bunch charges around 1~pC or even less enables the generation of ultra-short, coherent pulses with significantly higher brightness, opening the path to explore processes at attosecond timescales [1]. Similar requirements exist for next-generation ultrafast electron diffraction (UED), which demands sub-pC bunches and arrival-time monitoring with...
