9.3 keV, 1-35pulses, stable delivery ~600uJ
*General alignment of MID branch to the DES
*Commissioning of CRL2 (MID_XTD6_CRL) together with EEE after change to close loop in the maintenance period and alignment of lenses, characterization of beamsize using the X-ray eye at the sample position.
*Alignment of spectrometer in DES

9 and 10keV beam, up to 30 bunches, significant drop in intensity in the morning and in the evening.

Activities:

Commissioning of EH MIRR device

Preparation of user experiment at 10keV with lenses and monochromator

- finalized the flatfields of the AGIPD at 0.5 MHz
- optimized the performance of the beam (now 850 - 950 uJ)
- measured flatfield and darks for the Jungfrau detector
- optimized the instrument alignment of FEL beam and ALAS to the center of rotation
 

alignment checks of the CRL2 device as well as the Mono - continuation of both devices together planned for tomorrow
flatfelds for EPIX & AGIPD (needed to be redone because of too low intensity during the previous measurements)
installation of the levitation device and first test measurements

Shift summary for 28th of Aug.
- Realigned the center of rotation. 
- MID took the seeded beam at about 120 uJ around 4 p.m. after the long intervention.
- Cross-checked the time zero with Bi 222 diffraction peak.
- Searching and collecting diffraction patterns from a single nanocrystal. 
The user will continue to find the optimized condition for the flux of X-ray and Laser. 

Shift summary for 29th of Aug.

- Conducted Time-resolved Bragg CDI experiment using 3rd harmonic pump laser. 
- Collected coherent diffraction patterns from Perovskite-oxide nanocrystals for various time delay and laser fluence. 
- Checked the correlations between the XGM, diamond detector in SDL, and two Jungfrau detectors running on interleave mode. 

Shift summary (p4239)
Achievements:
- HXSS beam at 10.5 keV at 400 uJ pulse energy
- MID beam alignment to DES
- aligned DES spectrometer for C220 reflection on Gotthard and flight path;
Issues:
-    Seeding crystal was stuck in parked position and could not be inserted back (late evening); to be investigated via ZZ access tomorrow

Milestones:
*Finish measurement program on the STO sample at room temperature
*Check mono fpitch and energy rocking curve
*Darks for AGIPD and JF
*take out mono, CRLs etc from the tunnel

Beam delivery:

*Beam was not available from 11:30 to 19:30. Returned to good conditions back at  ~2mJ, 10.5keV, 15bunches

• stable delivery of 1mJ at 18keV SASE
• succesful beamline alignment for MID (CRLs + M1 and M2) with mono.
• alignment of NAFO stack to DES and zyla camera with SASE and monochromatic beam
• setup of DES spectrometer for 18keV on 440 reflection with SASE
• timing of PP laser with perpendicular excitation condition with diode and YAG

Problems:
Mirror M2 needs 30min to move from SASE to Mono position

• stable delivery of 1mJ SASE at 18keV
• NAFO lens characterization with caustic scan
• successful detector calibration of AGIPD with LaB6 and alignment of Jungfrau to diffraction signal with LaB6
• test of ptychography with 18keV (not successful)
• successful setup of online holography analysis with test measurements

• Stable delivery of SASE at 18 keV. The intensity dropped slightly from 1mJ to 0.88mJ during the evening, but everything good.
• fixed the laser pulse-on-demand + FSSS scanning macro
• We take some images series of the laser drilling process for different laser fluences
• We started to take first time resolved data

• stable SASE beam delivery with 1mJ pulse energy
• we took data for different optical laser excitation fluences and delays
• we changed from the optical lock to the electronic lock to measure also longer delays.

The Si 0.5mm absorber of XTD1 attenuator seems to be damaged. First screenshot is with that one inserted. In the second screenshot, it is replaced with a Si 0.5mm from MID_XTD6_ATT.
