Detailed Description

Wrapper for particle definition.

Used to calculate momentum and kinetic energy and associate any other information required along with a G4ParticleDefinition instance.

Bad construction can throw a BDSException.

Author: Laurie Nevay

Constructor & Destructor Documentation

◆ BDSParticleDefinition() [1/4]

BDSParticleDefinition::BDSParticleDefinition	(	G4ParticleDefinition *	particleIn,
		G4double	totalEnergyIn,
		G4double	kineticEnergyIn,
		G4double	momentumIn,
		G4double	ffact,
		BDSIonDefinition *	ionDefinitionIn = `nullptr`,
		G4int	ionPDGID = `0`
	)

Constructor requires G4 particle definition as well as one of total energy, kineticEnergy or momentum. Only 1 of these can be non-zero (will throw exception otherwise). The others are calculated using the mass. The optional ion definition may be supplied to override the charge of the ion. The PDGID should also be supplied in this case too. ffact is typically 1 or -1 to flip the rigidity for convention.

Definition at line 37 of file BDSParticleDefinition.cc.

Here is the call graph for this function:

◆ BDSParticleDefinition() [2/4]

BDSParticleDefinition::BDSParticleDefinition	(	const G4String &	nameIn,
		G4double	massIn,
		G4double	chargeIn,
		G4double	totalEnergyIn,
		G4double	kineticEnergyIn,
		G4double	momentumIn,
		G4double	ffact,
		BDSIonDefinition *	ionDefinitionIn = `nullptr`,
		G4int	ionPDGID = `0`
	)

Alternative constructor for when we don't have access to the particle table information. G4ParticleDefinition can be updated later. Developer responsibility to ensure this matches the contents of this class. ffact is typically 1 or -1 to flip the rigidity for convention. As before only one of totalEnergy, kineticEnergy or momentum should be specified.
