started with data acquisition for the ptycho experiment with different geometries
started with XPCS measurements of capillaries using the FSSS
issues: beam size changed a bit compared to yesterday (a bit bigger now - most proberly due to the realignment of the mirror suppressing the higher harmonics in the beam)

continued with the evaluation of the XPCS analysis packages
investigated the effect of alignment optimizations and forced misalignments on the contrast directly with the online XPCS tool
checked additional standard samples

**X-ray delivery**
- 6 keV, ~2.8 mJ, stable delivery
**Optical laser delivery**
- ns laser for particle visualization
**Achievements/Observations**
- measured user sample for almost whole day (about 100 runs x 5 minutes)
- Julabo chiller (AGIPD) is still on target (-32 degree)
**Issues**
- MKB Ion pump error (issue fixed after resetting the device)
- NKB focus loosed. Focus reoptimized twice during the d2 shift |

**Optical laser delivery**
- ns laser for particle visualization
**Achievements/Observations**
- measured sample for almost whole day (about 100 runs x 5 minutes)
- Julabo chiller (AGIPD) is still on target (-32 degree)
**Issues**
- Continuous beam drift in the vertical direction: NKB focus was optimized almost every 2 hours
- Sudden intensity drop in SA1 when SA2 or SA3 changes the number of pulses. |

Worked on the XPCS analysis packages
measured the TetraPack samples
continued with the levitation device
issues:
- Jungfrau detector had an error - R. Shayduk restarted the device - it should be power cycled as described in the manual
- The bunch number selctor does not work - the system didn't accepted 150 pulse but moved it back to 30 pulses - the machine switched off the user selection - should be followed up tomorrow

X-ray delivery
12.5 keV, ~1.6 mJ
Achievements/Observations:
Collected almost 40 runs of the priority sample with 7 pulses per train using the Polypico injection system.
Issues:
Jungfrau controller issue when changing back to single cell adaptive to collect powder data with new geometry (solved together with DOC).
Pipeline issue after requesting single cell correction - still the same bug in the calibration pipeline, the pipeline has to be re-instantiated after the change. |

machine runs at 17 keV with about 1.2 mJ
achievements:
check of the Zyla & Shimadzu and trigger optimization or 1.1 MHz
installation of FEL shutter and optimization of position and opening time
optimization of instrument macros
issues
DAQ crashed when shimadzu is running with 2.2 MHz and 256 images - DOC worked on the problem in collaboration with DA as well as ITDM OCD. They will follow up on the problem when ITDM checked the issue (redmine ticket #214244)

optimization of the timing of the involved components (laser, cameras, FEL)
generation of the first bubbles in water
issue
several times, the beam lost the position in the tunnel - it disappeared on the last tunnel imager. based on the motor parameter of the mirrors, no motion caused this. the position information of the XGM also did not show any strange values
