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.
