Help for X Cavity Launch FeedbackThis Help screen applies to the LTU Feedback. TheLTU Feedback adjust XCQT12 and YCQT12 corrector magnets in order to maintain the desired beam position at BPMT22.
This screen is arranged in three sections; States, Actuators, Measurements.
STATES:
This is a plot of all the states being maintained by the x cavity launch feedback. If the feedback is active, then the plot for each state will be continuously updating with calculated state data. The X and Y Position states share a plot. The plot lines are color coded with the State name to the right.
MEASUREMENTS:
This is a column of plot of the measurements being taken for the x cavity launch feedback. If the feedback is active, then the plot for each measurement device will be continuously updating with the measured data used in the feedback. The BPM X readings and BPM Y readings share one plot. The plot lines are color coded with the BPM name to the right.
ACTUATORS:
This is a column of plots of the actuators being controlled by x cavity launch feedback. If the feedback is active, then the plot for each actuator 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.
