Replay

  • ./replay
  • Allows access to log entries and graphs.

Instrument

Sample Motion

  • Sample motion uses diffractometer. Sample stage is on "horizontal controls" (diff_xh, diff_yh).
    • diff_xh : moves sample inboard/outboard.
      • Positive motion moves sample outboard (left, beam POV); i.e. beam moves right along sample.
      • Negative motion moves sample inboard (right, beam POV); i.e. beam moves left along sample.
    • diff_yh : moves sample up/down.
      • Positive motion moves sample up; i.e. beam moves down along sample.
      • Negative motion moves sample down; i.e. beam moves up along sample.
    • diff_zh : moves sample along beam.
  • Diffractometer also has stages on a "vertical" tower. Because these stages are sitting on a rotation axis (delta-like rotation), their translations (relative to sample) depend on delta.
    • diff_xv : moves sample inboard/outboard.
      • Positive motion moves stage outboard (left, beam POV); i.e. beam moves right along object.
      • Negative motion moves sample inboard (right, beam POV); i.e. beam moves left along object.
    • diff_yv : moves sample up/down. Assuming rotation stage is 180°:
      • Positive motion moves sample down; i.e. beam moves up along sample.
      • Negative motion moves sample up; i.e. beam moves down along sample.
    • diff_zv : moves sample along beam.

WAXS Detector Motion

  • delta : goniometer arm arcing up
    • Positive motion rotates RH (axis +vertical), a.k.a CCW (top POV); moves a downstream object left (beam POV); i.e. beam moves right along object.
    • Negative motion rotates LH (axis +vertical), a.k.a CW (top POV); moves a downstream object right (beam POV); i.e. beam moves left along object.
  • gamma : goniometer in-plane rotation
    • Positive motion rotates arm RH (axis +outboard), a.k.a CCW (sample POV); moves a downstream object down (beam POV); i.e. beam moves up along object.
    • Negative motion rotates arm LH (axis +outboard), a.k.a CW (sample POV); moves a downstream object up (beam POV); i.e. beam moves down along object.
