Simulation: Status and Plans

1
Simulation Status and Plans

• Toby Overview, gismo
• Masanobu Hit design, G4

A look back to 21 June 1999

Now

• It is GlastSim, WBS 4.1.D.2

Simulation in five easy pieces

1. Source description, including spectrum, rate,
   angular dependence, geomagnetic latitude, orbit
   orientation, GLAST inclination 
2. External geometry description
3. Concrete rendering of the detector for the
   simulation package 
4. Generation of hits (and thus a definition of the
   hit classes.)
5. Conversion of hits to digis for analysis

Simulatation status, plans

• Old glastsim converted to packages, still in use.
  Output available as Gaudi event service. Start of
  display.
• Geometry interface (Joannes talk) not critical
  path for balloon
• Simulation as a Gaudi service
• Geant4 LHCb has done it?
• Gismo on TO-DO list for THB
• Hit classes for interface to digi code see
  Masanobus talk.
