  1. Simulation: Status and Plans Toby: Overview, gismo Masanobu: Hit design, G4

  2. create instrument response glastsim.xml .irf read back response run parameters instrument.xml glastsim .tup instrument description reconstruct,write output ntuple merit standardanalysis A look back to 21 June 1999 Introduction, T. Burnett

  3. Now: • It is “GlastSim”, WBS 4.1.D.2 Introduction, T. Burnett

  4. Simulation in five easy pieces • Source description, including spectrum, rate, angular dependence, geomagnetic latitude, orbit orientation, GLAST inclination  • External geometry description • Concrete rendering of the detector for the simulation package  • Generation of hits (and thus a definition of the hit classes.) • Conversion of hits to digis for analysis Introduction, T. Burnett

  5. Traudl’s picture 1 4 3 2 5 Introduction, T. Burnett

  6. Simulatation status, plans • Old glastsim converted to packages, still in use. Output available as Gaudi event service. Start of display. • Geometry interface – (Joanne’s 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 Masanobu’s talk. Introduction, T. Burnett
