*Achievements :
- Generally rather successful with very high quality beam parameters
- We had a nearly steady 800 uJ+ HXRSS flux during the user run and ~ 4mJ SASE during the setup at HED. |

proposal 5700 finished on 04.05. The experiment used 352 pulses at 4.5 MHz and 18 keV to X-ray heat pressurized samples in diamond
anvil cells. Overall succesful on several samples.
Issues:
the requested 20.5 keV photon energy had too low pulse intensities
so we had to go down to 18 keV
pulse energies at 18 keV (300-400 uJ) were insufficient for some samples

Compensation of M2 RY motor for the case of Piezo off, posted by Kelin Tasca on 18 Jun 2024, 13:03

We plan to put the piezos of M2 off, in the (unprobable) case that this is the reason of the "jumps" in SASE3 trajectory.
Therefore, I measured the change on RY and RZ motors, to correct all the positions
Fig 1: initial position, Motors Ry=10.5425 and RZ=-14.7200 Piezo Ry =5 and Rz=5 |

We had some trouble with the DAQ. It was not able to start runs properly.
We got the following error messages:
