- 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. 
- Seeding optimization was ongoing. It will continue tomorrow morning. Still there is intensity loss during the energy scan.
- We might see second (maybe higher) photon energy component on the beam. (https://mylog.connect.xfel.eu/#narrow/stream/201-MID_6877_UrsStaub/topic/.E2.9C.94.20Troubleshooting/near/72056)
- The beam was focused with CRL 2 arm 4 and 5. A precise beam size measurement would be useful. 
- The timing of XFEL and PP laser has been found from a frosted-YAG on the X-ray eye. T0 = 1374.94.
- The air gap between the MPC and DES are closed. 
- The first user sample is mounted and delivered in the PUMA setup.
- The spatial overlap of XFEL and PP laser has been found at the sample position with YAG crystal.
- The substrate peak (th = 20.7, tth = 41.4) was found on the fluorescent screen. 
- The SDL diamond detector was aligned on the beam, and now move it out.

 
Tomorrow
- Continuing of optimization of seeding and improving the energy scan.
- Cool down the sample and search the film peak on AGIPD.
