The EPICS system is controlled by MEDM, which operates very similarly to that on the SAM85 White Beam main station. It actually can be controlled by any computer which is set up to run MEDM; X17B2SS1 has been set up to run it, but others could also be used. Begin by pressing the MEDM icon labeled Mono Side Station (NOT Mono Side Station (edit)). After a few seconds, the main MEDM window will open. This is based on the White Beam MEDM window, and some of the dialog boxes are left over, although they will still work for the white beam station.:
The Experiment Information window is the same as the Main Beam; The MCA window is also the same as for the Main Beam, and currently is not used for the Side Station.
The Motors window opens another menu:
MAR X moves the detector toward or away from the sample.
Mar downstream Y and MAR upstream Y moves each end of the detector table separately horizontally. SSTableY(Sum) moves both ends simultaneously.
Mar downstream Z w/brake and MAR upstream Y w/brake are motors equipped with brakes which move each end of the detector table separately vertically.. SSTableZ(Sum) moves both ends simultaneously.
Currently the monochromator has only one motor - the focusing motors are not yet installed.
The press sits on top of a horizontal circle, and can be moved in the Y direction relative to the center of that circle. It also can be rotated about the Z-axis of the circle. These are the first two motors. The remaining three move the circle itself with resect to the beam and detector.
The imaging camera is focused on a YAG/mirror which is between the press and the detector.
The MAR Shield is like a shutter, except that it blocks the entire front of the MAR. 0 means down (closed) and 400mm means up (open).
There are two windows which allow the user to monitor all motors, without being able to control them. Some of the motor numbers may be out of date.
The imaging system uses the Princeton Camera, which is also called Roper or Photometrics (due to corporate name changes).
