Preliminary Content (feel free to modify/comment it !) :

Introduction :

• Short summary of what background means for GLAST - reference to another poster ?

• General Beamtest setup to study the CU response to background sources

Main Tabs : Study of the different background sources

1. benchmark of hadronic process in GEANT4 with proton/pions at PS and SPS
2. hadronic interactions in MMS (PS proton runs)
3. positron annihilation events in MMS (PS positron and electons)
4. gamma-ray albedo (PS special fullbrehm runs)

Conclusion : 

• What we have learned thanks to the beamtest 

• How to tune GlastRelease to reproduce better these special classes of events
