Detailed Description

Implementation of a generic detector layer (base class for forward/barrel layers).

Each layer has a geometric attribute ('geomProperty') which depends on which kind of layer is actually created (radius for barrel layers, position z for forward layers). Furthermore, a thickness in radiation length is assigned which can vary throughout the layer.

getInteractionModels()

const std::vector<InteractionModel*>& fastsim::SimplifiedGeometry::getInteractionModels ( ) const

inline

Return the vector of all interaction models that are assigned with a layer.

This makes it easy to switch on/off some interactions for some layers.

References interactionModels_.

{ return interactionModels_; }

getMagneticFieldZ()

virtual const double fastsim::SimplifiedGeometry::getMagneticFieldZ ( const math::XYZTLorentzVector &  position ) const

pure virtual

Return magnetic field (field only has Z component!) on the layer.

Parameters

position

A position which has to be on the layer.

Returns

The magnetic field on the layer.

Implemented in fastsim::BarrelSimplifiedGeometry, and fastsim::ForwardSimplifiedGeometry.

getNuclearInteractionThicknessFactor()

const double fastsim::SimplifiedGeometry::getNuclearInteractionThicknessFactor ( ) const

inline

Some layers have a different thickness for nuclear interactions.

Right now only considered for TEC layers.

Definition at line 121 of file SimplifiedGeometry.h.

References nuclearInteractionThicknessFactor_.

{ return nuclearInteractionThicknessFactor_; }

getThickness() [1/2]

virtual const double fastsim::SimplifiedGeometry::getThickness ( const math::XYZTLorentzVector &  position ) const

pure virtual

Return thickness of the layer at a given position.

Returns the thickness of the layer (in radiation length) at a specified position since the thickness can vary throughout the layer.

Parameters

position

A position which has to be on the layer.

Returns

The thickness of the layer (in radiation length).

getThickness() [2/2]

virtual const double fastsim::SimplifiedGeometry::getThickness ( const math::XYZTLorentzVector &  position, const math::XYZTLorentzVector &  momentum  ) const

pure virtual

Return thickness of the layer at a given position, also considering the incident angle.

Returns the thickness of the layer (in radiation length) at a specified position and a given incident angle since the thickness can vary throughout the layer.

Parameters

position	A position which has to be on the layer.
momentum	The momentum of the incident particle.

Returns

The thickness of the layer (in radiation length).

Implemented in fastsim::BarrelSimplifiedGeometry, and fastsim::ForwardSimplifiedGeometry.

index()

int fastsim::SimplifiedGeometry::index ( ) const

inline

Return index of this layer (layers are numbered according to their position in the detector).

The (usual) order is increasing 'geomProperty':

• BarrelLayers: innermost to outermost
• ForwardLayers: -z to +z Makes it more convenient to navigate from one layer to the previous/next layer.

isForward()

virtual bool fastsim::SimplifiedGeometry::isForward ( ) const

pure virtual

Returns false/true depending if the object is a (non-abstract) barrel/forward layer.

Function to easily destinguish barrel from forward layers (which both inherit from SimplifiedGeometry).
