Thoughts

Photon Collection

1. DsChromaOpStackAction (based on DsOpStackAction to create and populate ChromaPhotonList structure)
2. DsOpStackAction doesnt actually store photons, it just provides classification fKill/fWaiting/fUrgent that directs G4 which stack to place things on
   • are the G4 stacks accessible without patching ?
   • convert that into ChromaPhotonList

Send to server

1. where to put the ZMQ context ? config via envvar

Handle Results from server

1. 1st try dealing pulling back the propagated ChromaPhotonList

Where is DsOpStackAction hooked up in NuWa ?

Simulation/DetSim/genConf/DetSim/DetSimConf.py
Simulation/DetSim/src/DetSim_entries.cc
Simulation/DetSim/python/poolgun.py             giga.StackingAction="DsOpStackAction"
Simulation/DetSim/python/DetSim/OpStack.py      opstack = DsOpStackAction("GiGa.DsOpStackAction")

GiGa hookup, Simulation/DetSim/python/DetSim/OpStack.py:

80     from DetSim.DetSimConf import DsPhysConsOptical
81     optical = DsPhysConsOptical("GiGa.GiGaPhysListModular.DsPhysConsOptical")
82     optical.CerenPhotonScaleWeight = 3.0
83     optical.ScintPhotonScaleWeight = 3.0
84     optical.UseScintillation = False
85
86
87     from DetSim.DetSimConf import DsOpStackAction
88     opstack = DsOpStackAction("GiGa.DsOpStackAction")
89     detsim.giga.StackingAction=opstack
90     opstack.TightCut = False
91     opstack.PhotonCut = False
92     opstack.MaxPhoton = 1e6

How to make ZMQ call from inside C++ code ?
