MC05: Longitudinal Diagnostics and Synchronization

Invited Oral Presentation

Ultrashort bunch length and longitudinal beam profile measurements are essential for characterizing electron beams in short-pulse accelerators, including free-electron laser facilities and novel accelerator concepts such as EuPRAXIA. A single-shot longitudinal diagnostics approach based on broadband spatial imaging of coherent transition radiation (CTR) in the THz region, combined with...

MC05: Longitudinal Diagnostics and Synchronization

Invited Oral Presentation

Ultrafast electron diffraction (UED) is a powerful tool for probing transient structural dynamics, however, its temporal resolution is fundamentally limited by laser-electron beam time of arrival jitter. To address the need for sub-10 femtosecond precision, we utilized a 4.76 GHz two-cell cavity-based Beam Arrival Monitor (BAM) designed to achieve high sensitivity at extremely low bunch...

MC05: Longitudinal Diagnostics and Synchronization

Contributed Oral Presentation

To measure longitudinal profiles at picosecond resolution, optical diagnostics using Cherenkov Radiation (ChR) must generate light with sufficient intensity, ensuring propagation to a detector with minimum dispersion and attenuation. Existing radiators (ChR generation media) exhibit a trade-off between ChR intensity and dispersion, with larger radiators creating higher ChR intensity at the...
