SCT Japan software Meeting
First Meeting at June Reference computer at
Okayama and Tokyo

Material Evaluation by Nova model
2D plot to check Material. Points come form
single particle
5
Hit data creation

• Local Hit position given by G4
• Hit data recorded using Moritas RootIO tool in
  FADS
• Histogramming routine modified from Tile Cal.
  Example written by Ikuo Ueda of Tokyo
• Hit data entry point, exit point, copy number,
  Energy deposit

6
Toy Digitization

• Test program was created.
• Read Root file
• Printout strip number and cluster size just from
  track length in the cell
• Energy deposit on sensitive detector is improper.
  Investigating.

7
Material evaluation

• Barrel module material check
• FADS/Goofy
• Drawing web archive was created by Taka Kondo.
• Material evaluation is proceeding at Okayama
  Univ.

Fine Drawings Material table
Geant4 Fine Geometry
Coarse Drawings Material table
Check distributions of X0 and lI, and total weight
Geant4 Coarse Geometry
Use FADS/Goofy for time being

An example of Material table
Almost all parts are listed with their
dimensions, densities, and material
compositions. Originated by Y. Unno (KEK)

Future Plan

• Self-education
• GEANT4,FADS/Goofy, NOVA(MySQL),
• Geometry, Hits/Digitization,
• 2day C/UML class for skill up on December
• Athena software installation to Okayama Univ. and
  other institutes.
