Issue, posted by Peter Zalden on 06 Feb 2025, 23:02

We observed a damage spot on the SA1 FEL imager. It moves with the target holder, but not sure if its damage on the optical mirror or on the target itself.
This issue is not critical, but can become problematic in case one wants to determine beam size or state of optics (ATT or CRLs) upstream. |
