Run Plan
- To-do List:
- Geometry is in gdml format, need to get correct Radiator, Collimator, Beamline, PhotonDump geometry.
- Add sweep magnet and electrondump geometry in gdml format.
- Complete: Include the Bubble Chamber geometry using the Bubble Chamber STEP file (change .txt to .stp): media:BubbleChamber.txt.
- Geometry has been created and is on github, BubbleMother.gdml and all daughter files
- The beamline STEP file will be ready very soon. When? Last file recieved was BubbleChamber again 6_24_2014.
- GEANT4 uses models that calculate wrong photo–nuclear cross sections (see below). GEANT4 does not allow for user’s cross sections. What to do?
- Use GEANT4 to produce the photon spectra impinging on the superheated liquid.
- Fold the above photon spectra with our cross sections in stand-alone codes.
- Could we not create a correct physicslist.cc in geant4 instead?
- GEANT4 Photon-Inelastic Model: CHIPS Gamma Nuclear has this cross section for our reaction:
- The simulation below is outdated and doesnt work with gdml. See github for correct version.
- Quick start for the simulation: media:G4_BubbleEx_README.txt. There is also a README file that comes with the example.
- Bubble Chamber GEANT4 Example (change .txt to .tar): media:BubbleEx96.txt
Compiling/Running Simulation (BubbleEx)
- Using the ifarm or jlabl4 nodes
