18 Feb 2023, 23:37 Together with the last shift members, we continued shooting laser on Cu 25 um thick wire for another 2 hours. We got excellent quality x-ray imaging with a series of time delay up to several ns (eLog ID 39). X-ray imaging is now commissioned. The magnification was x7.5.
19 Feb 2023, 01:30 We tried to go to x20, but we couldn't find the x-ray beam. We even put the burn paper in front of the Optique Peter to verify the x-ray position, but still we couldn't see anything on the Optique Peter. Probably the x-ray was too weak. This activity was done with CRL4b "in", so the beam size was big on the Optique Peter. Next step is to remove the CRL3b and do the same exercise.
19 Feb 2023, 03:00 We switch to CRL4a (upsteam of the sample) and aligned.
19 Feb 2023, 03:30 In parallel, PAM work: added 10 mm thick SF57 on the spectral arm. Time = 0 is established for both spatial and spectral arm. See eLog ID 33.
19 Feb 2023, 06:10 Put a mesh 2000 lines and do the focal scan. 1.5 % transmission. Att.1. The focus is around Axis_5 = 95-100 mm.
