Eighth SwissFEL Performance Workshop

Tuesday 13 Jan 2026, 08:00 → 17:30 Europe/Zurich

B6.-1D13 (Fachhochschule Nordwestschweiz Brugg / Windisch)

This is the eighth SwissFEL Performance Workshop to coordinate activities between machine and photon science for the upcoming year.
Workshop objectives:

• Review of beam dynamics progress (status of operation modes)
• Review of experiment progress and requirements
• Operations and scheduling
• Status and plans of key systems (accelerator and photon beam instrumentation)
• Discussion on topics of common interest

Zoom connection for off-site participants (same as for SEM):

Discussion: Suggested topics, to be continued in subsequent blocks

10 What is the experience with parallel operations and crosstalk in an increasing complex beamtime world (limitations, improvements)?

11 Where should we find the balance between stability and creativity? What are performance stability priorities?

12 Do we need more single pulse properties and diagnostics, faster feedback and more information?

13 Is our data analysis / online feedback fast enough? Do we have more needs for real-time analysis? What are acceptable delays and needs?
