Gabriel Musat L.L.R. – Ecole polytechnique ECFA-DESY Linear Collider Workshop Amsterdam, April 1-4, 2003

What is Mokka?  Developped at L.L.R. since the end of  Became « de facto » the reference for the calorimetry studies shown in the T.D.R.  Great news : became the Geant4 detailed simulation tool for all detector modules for the F.L.C. AND calorimeter prototypes. Gabriel Musat L.L.R. – Ecole polytechnique

Bug fix in Geant4-05 PI Reconstructed Energy less than 0.8 * Real Energy: –Before : 10% –After: 14.7% Gabriel Musat L.L.R. – Ecole polytechnique

The CGA API and the reconstruction  Example, a 50 GeV pi in ECAL :  the total number of X0 from the entrance point in ECAL is required Gabriel Musat L.L.R. – Ecole polytechnique

Mokka kernel - Common Geometry Access API New java/CGA sub-directory –CGARunManager class implemented using JNI –CGATest - example New examples/CGA sub-directory –F77 and C examples Gabriel Musat L.L.R. – Ecole polytechnique

Mokka detectors - new mask Karsten Buesser, January 2003

New sub-detector mask03 and new detector model D09M1 The mask doesn’t collect hits LAT module implemented with a material density equal to half tungsten density LCAL module not implemented Mokka detectors - new mask Gabriel Musat L.L.R. – Ecole polytechnique

Mokka detectors - New model “ProtoEcalHcalRPC” Ecal prototype: old prototype already available in Mokka Hcal prototype : a Hcal module in a cube format (~1 m 3 ), built with RPCs Y X Beam Gabriel Musat L.L.R. – Ecole polytechnique

Mokka detectors - in development (not yet integrated) Detector model DT01 reflecting the BRAHMS detector (Ties Behnke) NLC (XML) detector model (Ties Behnke) CMOS model of VxD (Damien Grandjean) SET implementation (LPNHE Paris) Hcal GEM (Venkat, University of Texas at Arlington) Gabriel Musat L.L.R. – Ecole polytechnique

Mokka kernel- future developments I Modify the registration scheme for new detector drivers –implement the Control class as a singleton –add a static member to the driver class Put reference material definitions in the DB Put specific materials in the sub-detector driver –add a virtual method –put material definitions in the sub-detector DB Improve the Event Display Gabriel Musat L.L.R. – Ecole polytechnique

Put MySQL scripts in the DB –a) identify sub-detector master parameters –b) compute size and placements of each detector piece as function of a) –c) translate b) into G4 objects Eventually put XML files in the DB Mokka kernel- future developments II Gabriel Musat L.L.R. – Ecole polytechnique

Mokka kernel- future developments III Add “ cellIndex ’’ method to CGA –( P S M I J K) => X Y Z – P, S, M = detector piece, stave, module numbers – I,J = the cell coordinates in the cells matrix – K = Sensitive (Si or scintillator or gas) layer number – X,Y,Z = the cell centre in world coordinates Gabriel Musat L.L.R. – Ecole polytechnique
