Geant4 Monte Carlo simulation for farPPD detector in Baksano Neutrino Observatory
Detailed review and entire diploma project: https://github.com/artem-phys/TmCryst
The farPPD facility is located in BNO and looks as shown in the photo:
The experimental installation consists of coating with borated polyethylene, lead coating, and copper housing inside.
The detector is located in the inner chamber, the air from which is not pumped out.
It's not what you thought, it's an experimental sample:
The bag is placed on the movable parts of the experimental installation, that can be lifted back
The sample is contaminated with americium, and thus, isotropically emits gamma particles of energy E=59.5409 keV. The decsription of particle generations is located in ExG4PrimaryGeneratorAction01.cpp
If you run the project without command line args, the visualisation starts:
A slight dead layer, that is not sensitive in the detector, present in this modeling. Also, you can see tracks of the particles in the following screenshot:
