Radiation Maps

T.Ruf, June, 2009

Radiation Map MC09 using LocalTags["DDDB"] = ["ot-20090519"]

horizontal axis: azimuth angle phi [degrees],  vertical axis: pseudo rapdity h
The average values for radiation length are obtained by integrating over phi and 1.9< h< 4.5
 

 

 

 

 

 

 

 

 

 

 

 



Radiation Map MC09, OT Bug

horizontal axis: azimuth angle phi [degrees],  vertical axis: pseudo rapdity h

Material used:

Use TransportSvc for radiation map

A) Radiation Map (DC06, XMLDDDB v30r3), Simplified Geometry (SQLDDDB v2r2)

B) Radiation Map (RTTC)

C) More details in Velo Exit window

to be compared with GEANT3 / Geantino results (SICBMC) --> here

other remark: transport service reports about many errors during computation, see log file.

 

 

More details for the VELO exit window:

Connection of exit window to beam pipe contributes significantly to the material budget.
