  1. Digital Calorimeter Simulation J.Yamada (Shinshu U)

  2. Purpose Using Geant4 simulation. I compare digital calorimeter with analog, and estimate ability of digital.

  3. Calorimeter lead 1m×1m×8mm sci 1m×1m×2mm Sandwich Hadron Calorimeter ×100 Layers 1m×1m ・・・ incident 1m

  4. Analog lead 1m×1m×8mm sci 1m×1m×2mm ×100Layers measure all energy each layer Measure Energy Digital lead 1m×1m×8mm sci 1cm×1cm×2mm ×10000 ×100Layers measure number of all hits Nhit Digital Calorimeter

  5. MIP(minimum ionizing particle) 0.32MeV = 1MIP

  6. Measure Data of 1event analog digital Nhit e ：79 hits π ：101hits MeasureEnergy e ：109MeV π ：111MeV

  7. Histogram of electron（4GeV、1000event） analog digital Mean ：102.8MeV Sigma ：10.41MeV Mean ：35.39hits Sigma ：5.467hits

  8. Histogram of π（4GeV、1000event） analog digital Mean ：113.9MeV Sigma ：34.43MeV Mean ：35.59hits Sigma ：9.027hits

  9. Threshold Dependence(Energy Resolution 1) electron π

  10. Threshold Dependence(Energy Resolution 2) electron π

  11. Threshold Dependence(Nhit) electron π

  12. Measure Energy , Nhit（Incident Energy Dependence） analog digital

  13. Energy Resolution（Incident Energy Dependence） π electron

  14. Cell Size Dependence（Measure Energy , Nhit） π electron

  15. Cell Size Dependence（Energy Resolution） π electron

  16. Compare with Experiment π electron

  17. Summary I can simulate digital calorimeter with Geant4. Digital is expected equal ability to analog of hadron calorimeter.
