Monitoring the Beam Line

Back to SBS Shift How-To

To monitor the Hall A beam line components, 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 [option]

The options are:

• main-monitor: A top level view of the beam line, including the differential momentum dp/p, beam mode (CW or tune), and select BPMs.
• raster: Tracks the raster magnet currents and set points.
• see-bpms: Tracks the beam position monitors (IPM1H04A and E), both x and y positions.
• bcms: Tracks the beam charge monitors.
• moller: Tracks the Moller quadrupole magnets, target, and dipole magnet.
• ion-chambers: Tracks ion chambers near the target pivot.
• orbit-lock: Tracks specific BPMs that are important for keeping the beam on the nominal orbit en route to the target.
