Detailed Description

A vector of BDSBeamlineElement instances - a beamline.

This will calculate and construct a beamline as BDSAcceleratorComponents are added in sequence - ie it calculates their placement positions and rotations with respect to the start of the beamline as well as their s position in curvilinear coordinates.

Note, this is not a singleton as geometry hierarchy can be introduced by placing beamline components inside parent volumes and therefore creating a new beamline of parents. It can also be used to create multiple beam lines.

Constructor & Destructor Documentation

◆ BDSBeamline() [1/2]

BDSBeamline::BDSBeamline	(	const G4ThreeVector &	initialGlobalPosition = `G4ThreeVector(0,0,0)`,
		G4RotationMatrix *	initialGlobalRotation = `nullptr`,
		G4double	initialSIn = `0.0`
	)

Versatile basic constructor that allows a finite position and rotation to be applied at the beginning of the beamline in global coordinates. Remember the maximum extents of the beamline will also be displaced. The default constructor is in effect achieved via defaults.

Member Function Documentation

◆ AddBeamlineElement()

void BDSBeamline::AddBeamlineElement ( BDSBeamlineElement * element )

Add a pre-assembled beam line element. In this case, the coordinates will have been calculated external to this class and as such, it's the responsibility of the developer to make sure the coordinates are correct and do not cause overlaps. This will be useful for tunnel construction for example or for a non-contiguous beamline. Subsequent components added via the AddComponent() method will be appended in the usual way to the end coordinates of this element.
