Sti vs Geant Energy Loss

First look at energy losses as seen by Geant and Sti. This is for a single slice at z=-3 cm

Geant Sti
 

Conclusiona and Action Items

  • The volume segmenation seems to be working and is in the CVS trunk now
  • Overal material distribution in Sti resembles the original Geant
    • SSD geometry from latest code in offline/hft is a simple tube averaging the mother volume
  • Sti overestimates energy losses w.r.t. the Geant calculations by a factor of 2-10
  • Still need to check if the recent Victor's dE/dx fix will help the problem
