This class generates a vertex of a neutrino-electron elastic scattering. It is strongly based in an initial implementation by Joe Formaggio and an adaptation for a beam by Bill Seligman. The event generation for solar neutrinos is a bit more complicated and therefore the whole class was virtually re-written since then. The ES cross-section is now determined in a separate class. This class is responsible for performing the kinematic propagation.

REVISION HISTORY:

• 02/09/2005 J. Formaggio (UW):
  • Original implementation
• 21-Jan-2006 Bill Seligman:
  • Converted to Geant4+GLG4Sim+RAT
• 18-Feb-2011 Nuno Barros:
  • Updated to accommodate the new solar generator, which is now used by default.
  • Completely refactored to improve the cross-section calculation on a different class (imported from QSNO).
  • Prepare ground to return both the electron in the neutrino in the generated event (only electron for now).
• 02-Jul-2012 N. Barros:
  • Removed the usage of Geant4 default streamers (G4cout) to use RAT Log mechanism instead.
• 02-Aug-2012 N. Barros:
  • Reintroduced the compatibility with the combo generator, for simulation of simple cases.
  • The messenger options are available or not depending on who is the parent generator (disabled if it is solar).
  • Changed the "simple" data types from G4XXX to C++ core types.
• 14-Aug-2012 N. Barros:
  • Solved some issues with the compatibility with the combo generator.
  • If the direction is set to 0,0,0 the generator now produces a random direction at each event.
• 26-Nov-2014: Matt Strait: Doxygen fixes.
• 17-Jul-2017: Modified for RAT-PAC

Member Function Documentation

GetDBName()

const G4String RAT::VertexGen_ES::GetDBName ( ) const

inline

Getter of the DB entry to input the spectrum from.

Returns

name of the DB name.

GetFlux()

G4String RAT::VertexGen_ES::GetFlux ( )

inline

Return the flux being generated.

Returns

Database key of the flux being used in this instance of the generator.

GetHelper()

ESgen* RAT::VertexGen_ES::GetHelper ( )

inline

Returns

the helper elastic scattering generator object.

GetNuFlavor()

G4String RAT::VertexGen_ES::GetNuFlavor ( )

inline

Returns the neutrino flavor being generated.

SetDBName()

void RAT::VertexGen_ES::SetDBName

(

const G4String

name

)

Setter of the DB name. Defaults to \'SOLAR\'

Parameters

[in]

name

of the database entry to look at.

SetFlux()

void RAT::VertexGen_ES::SetFlux

(

const G4String

flux

)

Auxiliary method to set the flux to be generated.

The flux can be any entry existing in the database defined in the constructor. For the case of solar it should be one of the solar fluxes (pp,pep,hep,be7,b8,n13,o15,f17). It looks up the corresponding spectrum in the SOLAR.ratdb file.

Parameters

flux	Key to the database entry. In case of solar it should be the corresponding flux.

SetNuFlavor()

void RAT::VertexGen_ES::SetNuFlavor

(

const G4String

flavor

)

Auxiliary method to set the neutrino flavor being generated.

Parameters

flavor

Flavor key passed to the RAT::ESCrossSec class. It can be one of (nue,numu,nuebar,numubar).
