The corrector magnets are two pairs of coils positioned along the beam line near the SBS magnet in order to minimize the deflection of the electron beam en route to the high-power beam dump. They are controlled by Accelerator Division. One pair is called upstream, while the other is called downstream, referring to their location relative to the target pivot; upstream is closest to the target pivot, while downstream is furthest from the target pivot.
To monitor the corrector magnets, run the following in a terminal to bring up a GUI that will show the magnet currents as a function of time:
ssh to adaq2 && ./start-beam-chart.sh correctors
