Adam Round | SPB | Shift end | On Shift: TS, FT, CK, AR, PS
X-ray delivery
8.951 keV, 1.6 mJ up to 200 pulses at 0.5 MHz (intesity drops off at end of train)
Achievements/Observations
Beam trajectory and focusing re-established at 8.951 keV
Temporary beamstop verified position for sweeping - confirmed by eric
Beam sweeping in synchronisation with pulse trains observed!
slit window assembly remounted and beam is going through to back of hutch in perparation for optimisation next shft |

Abhisakh Sarma | SPB | Shift summary | X-ray delivery
- 7.0 keV, up to 202 pulses at 564 kHz, 1.0 mJ.
- X-ray beam pointing changed at around 18:12 and it affects nano KB focus (from ~200nm to ~1um).
Optical laser delivery
- ns laser for jet illumination
Achievements/Observations
- Detector moved the most upstream position (~1.5 m sample to detector distance)
- BG measurement with water, buffer low salt
- Silver Behenate measurement for geometry file (mostly for detector distance)
- Data collection for different sample (pure) concentrations

Abhisakh Sarma | SPB | Shift summary | **X-ray delivery**
- 7.0 keV, up to 202 pulses at 564 kHz, 1.0 mJ.
**Optical laser delivery**
- ns laser for jet illumination
**Achievements/Observations**
- Data collection completed for all the requested samples from user.
**Issues**
- Run repeater behave once abnormally. Run repeater started with 30 minutes duration, but the first run (run #238) stopped after 40 seconds and next run (run #239) started.
