The late shift on the 13th fixed remaining problems with the DLD and the calibration pipeline.

The night shift was then able to collect data on O2 using the two-color mode. Systematic studies were done at different photon energies for both colors. This was done for full FEL intensity and 10%.

The day shift started to investigate if we see an effect changing the delay between the two colors. This turned out to be difficult because we lost the second color when changing the delay. BKR retuned for us with a delay.

Afterward, we asked BKR (Mathias and Mark) to re-tune the two color setup for short pulses.

Upcoming late and night shift should collect more data using the short pulses. Keep in mind to check and record the single pulse FEL spectrum upon each change on the undulator settings.
