X-ray delivery
10.65 keV, up to 339 pulses at 1.13 MHz, 1.6-1.8 mJ.
12.4 keV, up to 30 pulses at 1.13 MHz, 1.0-1.2 mJ.
Beam not
aligned to the crosshair at 12.4 keV, but we could work with it as it is to avoid further tuning.
Overall stable delivery.

beam parameters: 20 keV, 300 uJ, 352 pulses
continuation of user programe.
Machine performance very good for trying the 20 keV the first time. Experiment also going well.

*Vacuum issues: There seems to be a leak in the arm nr. 6 (2.4mm CVD Diamond). This has escalated to trip several times the vacuum sector interlock.
VAC will do an intervention to XTD1 with broken interlock tomorrow morning starting 9am to remove arm 6 permanently and putting a blind flange instead.
*We can measure for today with the 2.4mm CVD Diamond inserted into the beam. |

* First half of the day was used to optimize seeding performance
* Cryo issues started at 6 pm; were resolved by 9:30pm
* After some tuning, we observed very nice seeding performance around midnight (ratio better than 1:1) |
