Hello,
I've installed PANDARoot at home on a 64 bit LINUX machine and I switched CKOV(1) in g3Config.C, but if I run simulations of PANDA Barrel DIRC with Geant4, I don't see any optical photons! (With Geant3 everything is ok)
Can somebody tell me where to switch them on?
I use feb11 external packages if this matters.
Thank you.

Hi,
To switch on the optical properties with G4 you have to switch it on in the gconfig/g4Config.C
| Quote: |
TG4RunConfiguration* runConfiguration
= new TG4RunConfiguration("geomRoot", "QGSP_BERT_EMV", "stepLimiter+specialCuts+specialControls");
|
here you have to add "optical" to the physics lists i.e:
| Quote: |
TG4RunConfiguration* runConfiguration
= new TG4RunConfiguration("geomRoot", "QGSP_BERT_EMV+optical", "stepLimiter+specialCuts+specialControls");
|
see the g4Config.C for more options.
regards,
Mohammad
