This header declares the PlasmaMLPALLASRunAction class, which inherits from Geant4's G4UserRunAction to manage actions at the beginning and end of each run. It handles:

• Collection and storage of run-wide statistics
• ROOT file and tree creation for data output
• Synchronization in multithreaded runs
• Coordination with primary generator and geometry configuration

The associated RunTallyGlobalInput struct stores simulation configuration parameters and beamline element settings for the entire run.

Data recorded here typically includes:

• Initial beam parameters
• Magnet gradients and lengths
• Detector and collimator configurations
• Collected measurements from various beamline elements

Note

This class interacts closely with:

• PlasmaMLPALLASPrimaryGeneratorAction
• PlasmaMLPALLASGeometryConstruction
• Event-level statistics classes such as RunTallyQuadrupoles
