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):

11:10 What is the experience with parallel operations and crosstalk in an increasing complex beamtime world (limitations, improvements)?

11:15 Where should we find the balance between stability and creativity? What are performance stability priorities?

11:20 Do we need more single pulse properties and diagnostics, faster feedback and more information?

11:25 Is our data analysis / online feedback fast enough? Do we have more needs for real-time analysis? What are acceptable delays and needs?
