Double Chooz Software

Getting Started with Double Chooz Software

1. Contact Dario Motta (dario.motta@cea.fr), John LoSecco (losecco@nd.edu) or Michel Obolensky (obolen@in2p3.fr) to get added to the software mailing list.
2. Contact Michel Obolensky (obolen@in2p3.fr) for a computer account at CC-IN2P3 and to get CVS access to the code repository. For CVS access he will need:
   • - Name
   • - Home laboratory/site
   • - reliable e-mail address
   • - a specific SSH public key (SSH V2 protocol)
   • - the account name you wish
   • See: https://cvs.in2p3.fr/doc-en.html
3. The CVS repository has web access via: https://cvs.in2p3.fr/dchooz/. The standard Double Chooz username and password can be used for web access to CVS.
4. Introductory instructions on using CVS can be found at: https://cvs.in2p3.fr/dchooz/HOWTO/CVS.HOWTO Click the "(download)" link to see the instructions.
5. The simulation is based on Geant 4.7.1p01. Root output requires that CERN Root be installed. Geant depends on CLHEP. The HBOOK output to Ntuples requires a version of CERNLIB. The simulation also works with Geant4.8.1.p01 and CLHEP 1.9.2.3
6. Most of the usefull software is in the DOGS directory.
7. The detector simulation is in the DOGS/DCGLG4sim directory and its subdirectories.
8. Most simulation work has been done, so far, with the ROOT output version of DCGLG4sim. See DOGS/DCGLG4sim/COMPILING for instructions.
9. After building the Monte Carlo it is usefull to test it with a standard run:
   "dcglg4sim_batch mac/std_test.mac".
   This will take some time to run. Progress is indicated by a time stamp at 5 minute intervals to standard output.
10. A set of usefull computing resources is listed at the bottom of this web page.

Double Chooz Software Task list. October 22, 2006

1. Electronics Simulation
2. Quality Assurance
3. Calibration software. Both to (1) create the calibrations and (2) use the calibration information to calibrate an event.
4. Pulse shape discrimination to distinguish electromagnetic energy deposition from hadronic (proton recoil) energy deposition.
5. A unified detector geometry and configuration system.
6. Event format
7. Software release system.
8. Take charge of keeping RAT up to date.

9. Light Pulser Generator
10. Non root access to the data
11. Reconstruction interfaced to the Monte Carlo
12. Plastic scintillator outer veto simulation. There is a proportional tube based outer veto simulation
13. Feature extraction. Code to turn the waveform digitizer information into hits that can be calibrated and then used for reconstruction.
14. More event graphics. Right now only the inner detector PMT's are shown.
15. Muon capture simulation
16. Muon reconstruction tracking for both stopped muons and through going muons.
17. Create realistic reflector cones. Right now an ideal Winston cone is available.
18. Anisotropic phototube response
19. Create and maintain a software web page.
20. Physics studies with the Monte Carlo.
    • Number of phototubes
    • Surface reflectivity
    • Winston cones
    • Scintillator optical properties
    • Other detector variations, anisotropies or inhomogeneities.
    • Muon response
    • Stopping muon response
    • Radioactive source response
    • Entering neutron response
    • Neutrino response
    • Supernova simulations
    • Understanding the difference between detector calibration source response and detector signal response.
