Detailed Description

Save the amount and location of energy deposition. It contains the global position of the starting point and stopping point of the track segment that created the hit. The energy should be assumed to be deposited uniformly between the two points (the length of the segment can, and should, be limited in G4, so that shouldn't be a bad assumption). Both the total and secondary energy deposition is saved. The definition of the secondary energy depends on the configuration of the simulation, but generally, it refers to the amount of energy going into scintillation.

double TG4HitSegment::GetEnergyDeposit ( ) const

inline

The total energy deposit in this hit.

Definition at line 43 of file TG4HitSegment.h.

{return EnergyDeposit;}

int TG4HitSegment::GetPrimaryId ( ) const

inline

The track id of the most important particle associated with this hit segment.

Definition at line 40 of file TG4HitSegment.h.

{return PrimaryId;}

double TG4HitSegment::GetSecondaryDeposit ( ) const

inline

The "secondary" energy deposit in this hit. Generally, this is used to help simulate the amount of energy emitted as scintillation light, i.e. opticalphotons, and is part of the total energy deposit. The remaining energy will be deposited as ionization. In this model (in argon), the mean number of quanta created will be <N_q> = (fEnergyDeposit)/(19.5*eV), N_q should be fluctuated around <N_q>, N_ph = N_q*fSecondaryDeposit/fEnergyDeposit, and N_e = N_q - N_ph. Thd fSecondaryDeposit value already includes the binomial fluctuation, so don't fluctuate N_ph or N_e.

{return SecondaryDeposit;}

const TLorentzVector& TG4HitSegment::GetStart ( ) const

inline

The starting position of the segment.

Definition at line 62 of file TG4HitSegment.h.

{return Start;}

const TLorentzVector& TG4HitSegment::GetStop ( ) const

inline

The stopping position of the segment.

Definition at line 65 of file TG4HitSegment.h.

{return Stop;}

double TG4HitSegment::GetTrackLength ( ) const

inline

The total charged track length in this hit. This includes the contribution from all of the secondary particles (e.g. delta-rays) that are included in this hit.

Definition at line 59 of file TG4HitSegment.h.

{return TrackLength;}
