  1. Simulation of Light Ion Fragmentation Experiments Using GEANT4 Iwan Cornelius, Faiza Bourhaleb, Roberto Cirio, Flavio Marchetto

  2. Torino INFN • Italian Heavy Ion Therapy Facility (CNAO) • Development of beam monitoring hardware • Treatment planning research • Physics of ion interaction • Radiobiology

  3. Fragmentation Models • Current TPS (ANCOD) requires fluence spectra of primary and secondaries with depth in patient f(Z,E,t)H2O • Information used with Radiobiological model to calculate equivalent dose • In past produced by GEANT3 w. FREESCO interface • Investigate models of fragmentation • Quantum Molecular Dynamics • JQMD + Interface to GEANT4 • GEANT 4.6.0 Includes binary cascade model

  4. Model Verification • Simulate fragmentation experiments • Schall (GSI): Fragment yields (Z>4) for varying thickness water target • Matsufuji (NIRS): fragment yields (Z>1) for varying thickness PMMA target • Gunzert-Marx (GSI): fragment spectroscopy and angular dependence (n,p,d,t,He-3,a)

  5. G4 Ion Physics • G4MultipleScattering • G4ionIonisation • G4HadronInelasticProcess • G4TripathiCrossSection • G4IonsShenCrossSection • G4BinaryLightIonReaction

  6. Schall et.al. 1996 • Beam : C-12 676 AMeV • Target : H2O (variable thickness, t) • Detection system : Ionisation Chamber f(DE) • Information : N(Z,t) /No

  7. Ionisation Chamber Target Beam Selection System Geometry

  8. Results

  9. Gunzert-Marx et.al. 2003 • Beam : C-12 200 AMeV • Target : H2O (T>>R) • Detection system : Detector Telescope f(DE, E), TOF system • Information : N(q,E,X)

  10. Start / IC Target Telescope q Geometry

  11. To do • Simulate other data from Schall 1996 experiments with heavier ions O, N • Simulate Gunzert-Marx experiment • Simulate experiment of Matsufuji et.al. • Quantitative comparison using statistical packages?

  12. Summary • Torino section INFN active in treatment planning system research for HIT • Investigating fragmentation model of GEANT4 • Comparison between TPS results using different models of ion fragmentation • Monte Carlo based treatment planning
