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 |

Ealier shift members managed to get a good quality image on Optique Peter by imaging the sample plane to the Optique Peter with downstream nanofocus
(CRL4b). The quality is far superiour compared to the one with upstream nanofocus, which does just a projection of sample (backlight). The decision is
to stay with the downstream CRL. They had a few full power shots. The problem of reading Zyla data when rotation = 0 is solved by Olly. He put the script |

Data for the Horizontal jitter at the HED Pop-In was observed during beam delivery on cw05 (03-05.Feb) and cw07 (14-16.Feb) (see attached pictures).
We have a similar base jitter in both periods of beam delivery to HED, ranging from a minimum of 50-60um to around 80-100um in both operational
weeks. |

SA3 SCS exit slit: the upper blade was detached from the motor and fall into closed position. Maurizio V. and F. Wolff-Fabris tried to move it out
of the beam by placing spacers to hold the blade up.
Bottom blade was moved down with the motors. Currently both motors are disconnected. |
