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

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

+* 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.
+* Diffractometer also has
+===WAXS Detector Motion==
+* delta : goniometer arm arcing up
+* gamma : goniometer in-plane rotation
