  1. Status of Mokka / Fluka Integration • Aim • Method • Current Status Nigel Watson / RAL PPD-Birmingham

  2. Aim • Systematic comparison between Mokka and Fluka implementation of test beam configuration • Particularly interesting for hadronic interactions • See DRW’s Geant studies • Want flexibility to • Adapt to new mokka detector models • Investigate full TDR type geometry • Original problems • Fluka geometry defined by data cards • Only limited geometrical structures supported • Repeated structures at 1 level only Nigel Watson / RAL PPD-Birmingham

  3. Method • Geomety and physics decoupled in G4 and Fluka • Wrappers for f77/C++ • Fluka authors’ tests • Simple detectors • Identical results Fluka,Fluka+G4 • T36 calorimeter: 81 layers Pb (10mm)-scint.(2.5mm) • Consistent results • My first test • Use T36 calorimeter as above [From ATL-SOFT-98-039] Nigel Watson / RAL PPD-Birmingham

  4. Initial T36 calorimeter tests • Normal Fluka use: calculate particle fluence through defined regions (x,y,z) (radiation damage, dosage, etc.) • Want complete flexibility in information output • Extract hits with user supplied “scoring” on boundary crossing in mokka format e.g. Lateral response of T36 to 10 GeV - Nigel Watson / RAL PPD-Birmingham

  5. Boundary Crossing Detection • User routine callable when boundary between volumes detected during tracking a particle • G4 replica or parametrised volumes Fluka “lattice volumes” • Not seen during tracking • Repeated placement of identical G4 physical volumes are seen • Solution (from Flugg author) • Use rudimentary drawing routine, gives user control at each step in tracking • For Mokka study itself, can use Mokka CGA to determine boundaries within drawing routine (Missing!) replicated volumes… Nigel Watson / RAL PPD-Birmingham

  6. Current status • Mokka running within flugg/Fluka framework • Using Mokka-01-00 • Flugg05 (Jan. 2003) • Fluka 2002.1b (Dec. 2002) • Procedure: start from Mokka release and remove: • all classes except for detector construction, detector parametrisation, magnetic field construction • corresponding #include, variable and class definitions in .cc/.hh • anything related to G4RunManager, DetectorMessenger • code where SensitiveDetector is set • interactive code, visualisation, etc. • Some difficulties, e.g. with Mokka SD which contains sensitive detector definitions and rotation matrices Nigel Watson / RAL PPD-Birmingham

  11. Ongoing work • Understand runtime warnings, e.g. • Check again Fluka user provided inputs, e.g. • low energy neutron cross-section • PEMF, etc., • Extract information using CGA to Mokka format • Compare with DRW’s work NavHistWithCount::NavHistWithCount createdNavHistWithCount::NavHistWithCount created==> Flugg FluggNavigator::UpdateNavigatorHistory(0xcbb7278) +fHistory=History depth=0Level=[0]: Phys Name=[WorldPhysical] Type=[N]) ...<== Flugg FluggNavigator::UpdateNavigatorHistory(0xcbb7278)WARNING - Attempt to delete the physical volume store while geometry closed !WARNING - Attempt to delete the logical volume store while geometry closed !WARNING - Attempt to delete the solid store while geometry closed !

  12. Summary • Identified “easy” way of comparing G4/Fluka • Cannot use G-Fluka, completely obsolete • Don’t want to use “standalone” Fluka • inefficient, for variations in geometry • Improved understanding, moderate progres • Integration with Mokka geometry OK with some work • Debugging phase, to understand Fluka/Flugg Nigel Watson / RAL PPD-Birmingham
