The ef command will put the instrument in a "Fixed final energy"
configuration.
The syntax of the ef command is:
ef value
where value is the stored energy value. Note that this command
does not drive
the analyzer to this value of ef - to do so, type:
drive ef
value
The ef command can also be accessed from the GUI
by selecting the Experiment
tab from the Setup
top-level tab. To change to a fixed final energy configuration
and/or the stored value of Ef, the green button at the bottom of the tab
must be changed from "Monitoring ...
Click to allow changes" to "Changing ... click
to monitor". Select "Fixed Final
Energy (meV)" from the pull-down menu, change the value for "Fixed Energy (meV)" and commit the
changes by clicking on the blue "Update
Parameters" button.
