During the night we worked on the temporal overlap between Relax laser and XFEL.
In the morning we noticed that the beam jitter is quite large (in and out of the aperture of the CRL4 lenses). There seems to be a correlation with the HED popin. We adjusted the TCC with x-ray and laser. Performed transmission scans.
We managed to see the direct beam on JF. Continued with sample alignment (grazing-incidence) and also aligned the beamblocks to block the direkt and the reflected beam. |
