Juncheng E | SPB | Shift summary | X-ray delivery
- 9.3 keV, 3.1 mJ, 214 pulses/train at 1.1 MHz and 132 at 0.5 MHz
Optical later delivery
- For jet illumination
Achievements/Observations
- Aligned IRU_SLIT-3 again
- Collected PCS data in fixed MG: a lot of diffraction for 5458, only very few for 7559.
- Collected Lysozyme data in fixed MG and adaptive gain.
Issues
- IRU_SLIT-3 right blade was too close to the beam. Physically shifted it by a few mm towards the dark side and improvised lead aperture added between IRU_SLIT-3 and inlinemic.
- LitFrameFinder cannot recognize dark runs for fixed medium gain. One needs to check box Disable DAQ Filtering (on LitFrameFinder scene) or enable Global Passthrough Mode in LitFrameFinder properties, when takes darks for fixed MG. |

Romain Letrun | SPB | Shift summary | X-ray delivery
- 11.56 keV, 1-352 pulses @ 1.13 MHz, 2.4-3.1 mJ. Stable delivery.
- Intensity gradient with long train better than previous shifts (~20% drop).
Optical laser delivery
- 840 nm, 50 fs, 564 kHz.
- Stable delivery.
- Issue with Treacy compressor motion. Could be solved, but required intervention on site by LAS and EEE OCD.
Achievements/Observations
- Calibration of HIREX GOTTHARD II data working after intervention of DOC/DRC.
- Finished PP laser setup.
- PP laser timed.
- Collected SFX data sets using AGIPD in different gain modes.
Issues
- All AGIPD dark processing attempts failed with random missing modules showing up in the reports.
- We were not able to reach the DRC to discuss the above issue earlier during the shift on either 98089, 98088, or 01715330920. DOC informed at end of the shift.
- HIREX had been removed from the SASE1 DAQ, preventing the GOTTHARD II preview from running, and the DAQ was left into passive state after someone had used it during the day with the XTD9 Shimadzu camera.
- Problem with the Treacy compressor delayed the final PP laser preparation, which then had to be done during beam delivery.
