Detailed Description

Top Level Event Producer - coincidences of different interactions separated in time and space in same event

Author

Jeanne Wilson j.wil.nosp@m.son2.nosp@m.@phys.nosp@m.ics..nosp@m.ox.ac.nosp@m..uk

first version : 16-July-2008

This generator simulates 2 different decays at different positions and different times in the same specified event window. It can be used for the purposes of studying pile-up as it will efficiently produce a sample in which each event is a coincidence. There is also the option of restricting the events generated to those with summed primary particle energy in a given range.

Member Function Documentation

AddExtra()

void RAT::Coincidence_Gen::AddExtra ( G4String  state )

virtual

add an extra interaction

GetExtraPosState()

G4String RAT::Coincidence_Gen::GetExtraPosState ( int  nint ) const

virtual

get name of position generator for extra interaction, nint

GetExtraState()

G4String RAT::Coincidence_Gen::GetExtraState ( int  nint ) const

virtual

return state of added interation nint

GetExtraVertexState()

G4String RAT::Coincidence_Gen::GetExtraVertexState ( int  nint ) const

virtual

get name of vertex generator for extra interaction nint

GetNExtra()

virtual int RAT::Coincidence_Gen::GetNExtra ( ) const

inlinevirtual

return how many extra states have been added

SetEnergyRange()

void RAT::Coincidence_Gen::SetEnergyRange ( G4String  newValues )

virtual

restriction on total (generated) energy of pair

SetExponentials()

void RAT::Coincidence_Gen::SetExponentials ( G4String  state )

virtual

Set exponential time constants to separate decays. Default is to give each vertex a random time in the event window but if this option is called the user must set a time constant, T, for each added vertex. First vertex is at t = 0, the rest have times selected from exponentials exp(-t/T) each exponential applies to the time since last vertex

SetExtraPosState()

void RAT::Coincidence_Gen::SetExtraPosState ( G4String  state )

virtual

set position generator for most recently added extra interaction

SetExtraVertexState()

void RAT::Coincidence_Gen::SetExtraVertexState ( G4String  state )

virtual

set vertex generator for most recently added extra interaction

SetPosState()

void RAT::Coincidence_Gen::SetPosState ( G4String  state )

virtual

position generator for base interaction

Reimplemented from GLG4Gen.

SetState()

void RAT::Coincidence_Gen::SetState ( G4String  state )

virtual

Basic state - first interaction type and position

Implements GLG4Gen.

SetTimeState()

void RAT::Coincidence_Gen::SetTimeState ( G4String  state )

virtual

Overall time state - time from one coincidence event to next

Reimplemented from GLG4Gen.

SetTimeWindow()

virtual void RAT::Coincidence_Gen::SetTimeWindow ( double  window )

inlinevirtual

time window over which 2 events considered coincident

SetVertexState()

void RAT::Coincidence_Gen::SetVertexState ( G4String  state )

virtual

vertex generator for base interaction

Reimplemented from GLG4Gen.
