Not sure if this is the cause of the fringes reported before, but at 5.6 keV there are clear cracks visible on the XTD2 Attenuators 75 umm and 150um CVD, see attached. There is also a little bit of damage on the 600 um CVD, but not as strong as the others.
At 5.6 keV we will need to use the thin attenuators. I will mention again in case this causes problems downstream.
Edit 8:50h: We do not observe additional interference effects in the downstream beam profile (see attachement 4) |
