Simulation objects for optical detectors.
This file contains the definitions of the classes which are stored in the event representing scintillation photons detected by the optical detectors.
A scintillation photon collection (sim::SimPhotons
) stores data for each photon which steps inside the optical detector volume. Currently the quantities stored are position, time, 4-momentum and the ID of the GEANT4 track emitting it. A sim::SimPhotonsCollection
is a set of sim::SimPhotonss
, one per optical detector in the collection.
The sim::SimPhotons
is filled in by the larg4::OpFastScintillation
class in LegacyLArG4
module and will be used to generate the optical detector response later in the simulation chain.
sim::OnePhoton
, sim::SimPhotons
and sim::SimPhotonsCollection
are all persistent under ROOT I/O.
The current implementation resembles that of an C++ STL container in some respects but needs more work before it is polished product.
