Pulse Picker

  • Rapidly shutter the X-ray beam
  • Buttons
    • Open DIA
    • Close DIA

Attenuators (10 Si filters of various thickness)

  • Control the incident beam intensity
  • Buttons

X-ray Focusing Lenses

  • Pre-focus the X-ray beam or produce a ~300 micron focus at CXI, it is a single lens instead of a lens stack
    • Buttons: Beamline -> Prefocus Lenses
    • The motor has X and Y control, but no Z control
    • Lens OUT position: Y = 94mm
  • Refer to the CXI logbook (CXI Shielding and X-ray Energy Verification Procedure) (hard copy) for combination of the lenses for different focusing powers (for different X-ray photon energies)
  • NOTE: every time we change the focusing configuration, we need to record the change and sign in the CXI logbook hard copy
