Geometry Setup[edit | edit source]
The geometry for the Geant4 simulation is defined in /home/jlabdaq/CDetMC/src/DetectorConstruction.cc
General Construction[edit | edit source]
- G4 GeometryManager
- Opens the geometry and removes optimizations (optionally, related to just the specified logical-volume).
G4GeometryManager::OpenGeometry(G4VPhysicalVolume* pVolume)
- G4LogicalVolume
- Constructor - sets member data and adds to logical Store, voxel pointer for optimization set to 0 by default.Initializes daughter vector to 0 length.

G4Material * pMaterial,
const G4String & name,
G4FieldManager * pFieldMgr = 0,
G4VSensitiveDetector * pSDetector = 0,
G4UserLimits * pULimits = 0,

| Plot Title | Description | Plot |
|---|---|---|
| C1 | Position of incident muons in the x, y, and z coordinates, and the time of impacts. we guess ¯\_(ツ)_/¯ |  |
| C2RA | The truth values used in the simulation. Primitive energy. The Theta and Phi angles when measured. The particle pdg value. |  |
| C3RA | The simulation results. Detector of hits on the scintillators. The measured mass of the particle is the interpreted PDG value. fingerID shows the event counts and which finger the events occur at. fingerED shows the energy deposited and how many times it occurred. fingerPMTID shows the PMTID's related to each scintillator and the number of incidents for each. Finger PMT Time shows the distribution of time values. |  |
| C4RA | Histograms for energy deposition and number of photo electrons |  |
| C7RA | Energy deposition vs number of photons |  |
| C8RA | Energy deposition vs number of photons |  |
| C12 | Shows the momentum of particles in each of the directions. |  |
| C13 | Event impact point distribution |  |
| C14 | Recorded incident impact points in the x, y, and z directions. |  |
| C33RA | Angle of incident ± π/2 |  |
