1. Imperial, 18/03/2003Nigel Watson / RAL PPD-Birmingham1 Status of Mokka / Fluka Integration  Aim  Method  Current Status

2. Imperial, 18/03/2003Nigel Watson / RAL PPD-Birmingham2 AimAim  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

3. Imperial, 18/03/2003Nigel Watson / RAL PPD-Birmingham3 MethodMethod [From ATL-SOFT-98-039]  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

4. Imperial, 18/03/2003Nigel Watson / RAL PPD-Birmingham4  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  - Initial T36 calorimeter tests

5. Imperial, 18/03/2003Nigel Watson / RAL PPD-Birmingham5 (Missing!) replicated volumes…  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 Boundary Crossing Detection

6. Imperial, 18/03/2003Nigel Watson / RAL PPD-Birmingham6 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

7. Imperial, 18/03/2003Nigel Watson / RAL PPD-Birmingham7 OperationOperation  Two stage process  First pass, to generate material definitions, fluka to G4 correspondance  Second pass, to run fluka with G4 geometry /home/nkw/lc/calice/flugg05/examples/fluggEx/emptyEx/src: wildcard *.cc -rw-r--r-- 1 nkw opal 23998 Mar 13 12:11 Control.cc -rw-r--r-- 1 nkw opal 4275 Mar 6 16:13 CGAInit.cc -rw-r--r-- 1 nkw opal 10139 Mar 6 09:46 TPC00.cc -rw-r--r-- 1 nkw opal 13878 Mar 5 11:46 SD.cc -rw-r--r-- 1 nkw opal 27482 Mar 5 11:44 Proto01.cc -rw-r--r-- 1 nkw opal 20384 Mar 5 11:40 Proto00.cc -rw-r--r-- 1 nkw opal 17489 Mar 5 10:46 CGAGeometryManager.cc -rw-r--r-- 1 nkw opal 24553 Mar 5 10:46 Ecal02.cc -rw-r--r-- 1 nkw opal 20648 Mar 5 10:46 Hcal02.cc -rw-r--r-- 1 nkw opal 30122 Mar 5 10:45 Hcal03.cc -rw-r--r-- 1 nkw opal 20115 Mar 5 10:45 HcalWMod.cc -rw-r--r-- 1 nkw opal 5052 Mar 5 10:36 Hodoscope00.cc -rw-r--r-- 1 nkw opal 10789 Mar 5 09:40 HECSD.cc -rw-r--r-- 1 nkw opal 6664 Mar 4 15:19 ECSD.cc -rw-r--r-- 1 nkw opal 5277 Mar 4 12:44 VSubDetectorDriver.cc -rw-r--r-- 1 nkw opal 8014 Aug 1 2002 SET00.cc -rw-r--r-- 1 nkw opal 2197 Aug 1 2002 Coil00.cc -rw-r--r-- 1 nkw opal 1529 Jul 22 2002 CGAUtils.cc -rw-r--r-- 1 nkw opal 4762 Jul 19 2002 Yoke00.cc -rw-r--r-- 1 nkw opal 3329 Jul 19 2002 Mask00.cc -rw-r--r-- 1 nkw opal 7795 Feb 20 2002 MySQLWrapper.cc -rw-r--r-- 1 nkw opal 29959 Feb 20 2002 MyPlacement.cc -rw-r--r-- 1 nkw opal 3333 Feb 20 2002 Field00.cc
