The Multiturn GUI

The Multiturn GUI provides functionality to set up and perform beam excitation with the AC Dipole or the ADT. Excitations feature automatic saving of turn-by-turn BPM data. This section will guide you through the GUI's layout and functionality.

The GUI is a Java application and is typically run from the CCM:

Have a working CCM running as lhcop, then navigate to LHC Control -> LHC Beam Measurements -> Multiturn.

After opening, the GUI should look like this:

After opening, select at the top of the GUI either the Acquisition BEAM1 or Acquisition BEAM2 tab, depending on the beam you plan on measuring.

Warning

It is recommended to not kick both beams from the same GUI, as it can lead to crashes and unexpected behavior. Open a separate GUI for each beam.

Closing Tabs

To avoid kicking the wrong beam accidentally, one can drag and drop the tab for the unused beam out of the GUI.

The following pages are available:

  • Safety Checks for how important checks to be performed for measurements.
  • Beam Excitation for how to excite the beam with either the AC Dipole or the ADT.
  • Scheduled Excitations for how to schedule and run AC-Dipole measurements with a set of predefined kick amplitudes.
