class ThinMapper : public Mapper

(Return to index)

Construct thin lens map.

The visitor class for building a FVps<double,6> for a beamline using a thin-lens approximation for all elements.

Approximations used:

• All active elements are represented as thin lenses, sandwiched between two drifts, each half of the element length.
• Drifts are handled with a second-order approximation.
• Geometric transformations ignore rotations about transverse axes and translations along the design orbit and truncate after second order.

Type:	Instantiable

  ThinMapper (const Beamline&,const PartData&,bool,bool) ;

  Constructor.
  The beam line to be tracked is bl. The particle reference data are taken from data. If revBeam is true, the beam runs from s = C to s = 0. If revTracl is true, we track against the beam.

  virtual void visitBeamBeam (const BeamBeam&) ;

  Apply the algorithm to a beam-beam.

  virtual void visitCollimator (const Collimator&) ;

  Apply the algorithm to a collimator.

  virtual void visitCorrector (const Corrector&) ;

  Apply the algorithm to a corrector.

  virtual void visitDiagnostic (const Diagnostic&) ;

  Apply the algorithm to a diagnostic.

  virtual void visitDrift (const Drift&) ;

  Apply the algorithm to a drift.

  virtual void visitLambertson (const Lambertson&) ;

  Apply the algorithm to a Lambertson.

  virtual void visitMarker (const Marker&) ;

  Apply the algorithm to a marker.
