Session 2: FEL Prize Talks

Invited Oral Presentation

The Compact X-ray Free-Electron Laser (SACLA) initially faced severe criticism that it would be unable to achieve effective laser amplification. However, SACLA smoothly achieved laser amplification after its construction and has become one of the world’s most widely used FEL facilities, capable of conducting independent experiments simultaneously with its three FEL beamlines. This presentation...

35. SACLA　XFEL Facility: Now and What's Next (MOY02)

Session 2: FEL Prize Talks

Invited Oral Presentation

Since the commissioning in 2011, SACLA has made continuous efforts to improve stability and XFEL performance with a focus on user operation. A variety of XFEL operation modes have been offered to users, such as two-color, self-seeded and attosecond XFEL. In parallel with XFEL operation, SACLA has been also playing an unique and important roll as a low-emittance injector of a storage ring,...

30. Toward zeptosecond FELs (MOY03)

Session 2: FEL Prize Talks

Invited Oral Presentation

Recent advancements in FEL science and technologies have made it possible to generate attosecond pulses in many FEL facilities by means of various methods. Such "attosecond FELs" definitely contribute to the progress of ultrafast science, by improving the temporal resolution in time-resolved measurements; however, we should recall that human desires are limitless! The next target may probably...

84. Electron and photon beam diagnostics and wakefield studies with corrugated structures (MOY04)

Dr Philipp Dijkstal (Paul Scherrer Institute)

Session 2: FEL Prize Talks

Invited Oral Presentation

Wakefield structures can generate strong transverse chirps (beam tilts) and thereby enable time-resolved beam diagnostics similar to transverse deflecting rf structures, but at a much reduced cost. Electron beam current and FEL power profile measurements using rectangular corrugated structures are routinely performed at SwissFEL and other facilities. Some of the data analysis methods required...
