Pulse Picker

- Buttons
- Open DIA
- Close DIA
Attenuators (10 Si filters of various thickness)

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
