We checked the XTD2 attenuators following the intervention from XRO (compar ewith elog:37, before the intervention).

The wavefront shows similar distortions with the 75 and 150 um as earlier, which is not too surprising since the cracks are vertical.

Attachments 6-7: Beam on FEL imager with XTD2 75 and 150 um CVDs
