This page provides brief notes/hints for using the CHX beamline at NSLS-II.

General

Status

Contact

  • Beamline: x1411
  • Floor coordinator: x5046
  • Control room: x2555

Controls

ophyd

  • Start:
    • cd ~
    • ./ophyd
  • Examples:
    • wh_pos() : motor positions
    • mov(diff_xh, 1.0) : move motor
    • movr(diff_xh, -1.0) : relative motion
    • movr([diff_xh, diff_yh], [-1.0,-1.0]) : multiple motions

Control System Studio (CSS)

  • Start:
    • run-css &
  • Use:
    • Ctrl+mousewheel : zoom

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
  • gamma : goniometer in-plane rotation

WAXS Detector

Cameras

  • camonitor
