X-ray delivery

  • 12.42 keV, stable delivery in single pulse mode with 1.9 mJ/pulse

Optical laser delivery

  • 532 nm ns-laser for sample pumping

Achievements/Observations

  • Collected protein crystal diffraction for three different samples with varying laser delay and fluence. LCP viscous jet sample delivery.
  • Stable CRL focus using tunnel collimation with 3 XTD2 lenses followed by 17 focusing lenses in SPB hutch. 2 um FWHM focus with <1um standard deviation in 'X' position.
    • 3 XTD2 lenses gives a round X-ray beam approx 1 mm in size, such that we are almost overfilling the CRL apertues in SPB.

Issues

  • Some initial jetting issues, which have now been solved.
