Beamline Coordinates

X-Y-Z

  • X: radial direction of the ring, horizontal, pointing outboard to the doors.
  • Y: vertically upward (against gravity).
  • Z: along the x-ray beam

X-H-F

Because we routinely deal with motions in 45°-tilted directions, H and F are introduced as alternative coordinates to Y and Z:

  • H:
  • F:
