SPB/SFX User Proposal 3333 Shift 2 Summary

X-ray delivery

• 9.3 keV, 1.7 mJ, 202 pulses @ 564 kHz

• 2 pulse trial @ 2.8 kHz (2.2MHz / 800). Doubled data rate for high viscocity jet. Seemed to work quite well although not expected to be a regular use mode!

Optical laser delivery

• Only 819 nm ns laser for the jet visualization

Achievements/Observations

• Data calibration issues solved (thanks to DRC / ITDM experts)

• Silicon wafer post sample attenuator was dismounted. elog: 45

• High viscosity jet delivery @ 10 Hz and 2.8 kHz (2 pulses / train @ max spacing)

• Photosystem-II (@ 41 mm AGIPD Z motor value, adaptive gain) elog: 85,86, various sample preparations

Issues

• ONDA restarts required

Instrument status

• Sample chamber and AGIPD turbos OFF, rough pumping ON

• shutters etc. closed

To do for next shift

• Catcher and shroud (inc windows) could do with a clean before any alignment (PEG delivery)

• Proceed with PCS users
