The feedback used the following parameters:
| EOS only P feedback parameters | |
|---|---|
| EOS calibration | 20 fs/px |
| Analysis method | Projection and find maximum of projection via max() function |
| Feedback on PV: | OSC:LA20:10:FS_TGT_TIME |
| Averaging over number of shots | 10 |
Performance during laser energy scans:

by the goose trigger. Below 10 % energy, the feedback stalled.

The plots show that already an automated p feedback is superior to a person adjusting laser target time by hand to keep timing stable
