Detailed Description

Abstract class that represents a component of an accelerator.

It must be constructed with a name, length (arc), angle it induces (x,z plane in the local coordinates of the component) in the reference trajectory and a string representing its type. The class has no concept of its position in the beamline or in global coordinates. This information is contained in an instance of BDSBeamlineElement.

This is an abstract class as the derived class must provide the implementation of BuildContainerLogicalVolume() that constructs at least a single volume, which would be assumed to be a container if greater geometry hierarchy is constructed. This is the minimum required so that an instance of the derived class will operate with the rest of the placement machinery in BDSIM. The derived class should override Build() to add further geometry. If Build() is overridden, the base class BDSAcceleratorComponent::Build() should be called first. This calls BuildContainerVolume() and sets the visual attributes of it.

The class provides deferred construction through the Initialise() function to allow two stage construction if it's required. So, although a derived class is instantiated, the geometry isn't constructed until Initialise() is called.

Note, the geometry of any derived component should be nominally constructed along local z axis (beam direction) and x,y are transverse dimensions in a right-handed coordinate system.

The 'length' of the accelerator component is the arc length, which corresponds to the angle given. The chord length is internally calculated from the arc length and the angle. Therefore, the chord length must never be given.

The optional input and output face normal (unit) vectors are w.r.t. the incoming / outgoing reference trajectory and NOT the local geometry of the component.

Constructor & Destructor Documentation

◆ BDSAcceleratorComponent() [1/2]

BDSAcceleratorComponent::BDSAcceleratorComponent	(	const G4String &	name,
		G4double	arcLength,
		G4double	angle,
		const G4String &	type,
		BDSBeamPipeInfo *	beamPipeInfo = `nullptr`,
		const G4ThreeVector &	inputFaceNormalIn = `G4ThreeVector(0,0,-1)`,
		const G4ThreeVector &	outputFaceNormalIn = `G4ThreeVector(0,0, 1)`,
		BDSFieldInfo *	fieldInfoIn = `nullptr`
	)

Constructor - this is the minimum information needed to create a BDSAcceleratorComponent instance. Methods in the class will allow the derived class to associate the appropriate volumes to the members of BDSGeometryComponent - the base class. The developer of a derived class should take care to set all members of BDSGeometryComponent in the derived class, including extents. Note, this class has arc length and chord length which are initially set to be the same, unless angle is != 0 in which case, the chord length is calculated from arc length. An associated beam pipe info instance can be attached if the component has a beam pipe. The input and output face normals should also be specified if non-zero. Additionally, a field info instance that represents a 'global' field for this component may be specified. Face normal (unit) vectors are w.r.t. the incoming / outgoing reference trajectory and NOT the local geometry of the component. The BDSBeamPipeInfo instance is associated with this class so that the survey output of BDSIM can query the aperture of any element.

◆ Build()

This calls BuildContainerLogicalVolume() and then sets the visual attributes of the container logical volume. This should be overridden by derived class to add more geometry apart from the container volume. The overridden Build() function can however, call make use of this function to call BuildContainerLogicalVolume() by calling BDSAcceleratorComponent::Build() at the beginning.

This tests to see if the length of the BDSAcceleratorComponent is shorter than the global step length in the global users limits and if so build a unique one for this component and register it (memory management). It's provided by the member userLimits. This will be nullptr until this function is called, which is called in this class's Build(). Putting it here makes the same G4UserLimits object available to all derived classes potentially saving creation of a duplicate object.

◆ OutputFaceNormal()

G4ThreeVector BDSAcceleratorComponent::OutputFaceNormal ( ) const

inline

Access face normal unit vector. This is w.r.t. the incoming / outgoing reference trajectory and NOT the local geometry of the component. Ie for an SBend with no pole face rotation this is incoming (0,0,-1). Does not account for tilt.

◆ SetAcceleratorVacuumLogicalVolume() [2/2]

void BDSAcceleratorComponent::SetAcceleratorVacuumLogicalVolume ( G4LogicalVolume * accVacLVIn )

inlineprotected

Assign the accelerator tracking volume - only callable by derived classes - ie not public. This is just setting a reference to the accelerator volume and it is not deleted by this class (BDSAcceleratorComponent) - therefore, the derived class should also deal with memory management of this volume - whether this is by using the inherited (from BDSGeometryComponent) RegisterLogicalVolume() or by manually deleting itself.
