Help for L3 Launch Feedback
This Help screen applies to all Launch Feedbacks currently commissioned.
The feedbacks adjust X and Y corrector magnets in order to maintain the desired beam position and angle at different points along the beamline.
This screen is arranged in three sections; States, Actuators, Measurements.
STATES:
This is a column of plots of all the possible states being maintained by the launch feedbacks. If the chosen feedback is active, then the plot for each state configured for the chosen feedback will be continuously updating with calculated state data.
At this time, the X and Y Position states, and X and Y Angle states each share a plot. The plot lines are color coded with the State name to the right.
MEASUREMENTS:
This is a column of plots of all the possible measurements being taken for the longitudinal feedbacks. If the chosen feedback is active, then the plot for each measurement device configured for the chosen feedback will be continuously updating with the measured data used in the feedback. The BPM X readings, and BPM Y readings, of all configured measurement devices each share one plot. The plot lines are color coded with the BPM name to the right.
ACTUATORS:
This is a column of plots of all the possible actuators being controlled by launch feedbacks. If the chosen feedback is active, then the plot for each actuator configured for the chosen feedback will be continuously updating with calculated settings.
Right-click on any plot, then choose 'perform auto-scale' to have the graph automatically choose an appropriate scale for the current data.
