Response of the GLAST-LAT Calibration Unit to sources of background
Responsible persons : TBD
People interested (Please Add your name here if you want to contribute)
- Johan Bregeon : hadronic interactions, albde gamma
- Carmelo Sgrò : positron annihilation
- Francesco Longo : hadronic process in GEANT4
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
- benchmark of hadronic process in GEANT4 with proton/pions at PS and SPS
- hadronic interactions in MMS (PS proton runs)
- positron annihilation events in MMS (PS positron and electons)
- 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
Material for the poster
- Simulated positron annihilation in the MMS (from BT-1356, event 4040)
