- DAQ was crashed after taking darks of AGIPD. It was solved by DOC and OCD.
- Laser could not switched from optical to RF lock. Solved by OCD (using doocs).
- Energy scan was attempted, which was not successful. |

- The seeding optimization result: Total 450 uJ (Seeding of 150 uJ + SASE of 300 uJ). BKR will be able to start optimization on Saturday
around noon if necessary.
- The pump-probe (PP laser and PuMa pulse) experiment data on the substrate peak was collected. |

- The seeding optimization is ongoing, which was not successful. Now we have a total of 170 uJ including SASE and seeding.
- The option to switch to SASE is relatively not complex and can be done with the support of BKR without a seeding expert. BKR expects to
provide about (more than) 1 mJ. To be discussed with user later. |
