• Simulation software updates
• Radiation shielding update from meeting with JLab

Attendance:

Attendance: Rakitha, Ciprian, Sakib, Juliette, Dustin, Cameron, Chandan, Wouter, Kent

Minutes

• Making GDML implementation guideline by Ciprian
  • Using nested volumes for regions and sub-regions
  • suggestions for variables and naming conventions.
  • Always run dos2unix on your files before committing a new file if you are on a windows OS
  • If you use tabs convert tabs to spaces in your editor
  • Use G4 materials as the first choice using G4_materialname
  • Use keep-out regions for each subvolume
  • Ciprian and Juliette implementing the beam pipe. The discussion is how to implement separately in different sub-regions. The hybrid area vacuum or He needs to finalized that way we may be able to use single sub volume for the beam pipe.
  • There is no beam pipe going through two magnets due to the vacuum within the magnets.
  • Create a directory for each daughter region and keep GDML files only in that region on the directory.
• Updates on Simulation development in general
  • Beam pipe implementation is in accordance to GMDL guideline we agreed - Ciprian
  • Shielding implementation is in accordance to GMDL guideline we agreed - Rakitha
  • Master and develop branches should work by simply checking out from GIT. New versions for master will be released every 3 months. Develop will have new features but not agreed on final versions so it may have some issues. The master branch is the working version for anyone to use.
  • Working on geometry development branch where geometry is tracked independently but we are not there yet.
  • Even with geometry is tracked independently master branch will have its own releaser of geometry tagged to it.
  • GIT tracking for geometry and code updates
  • use the wiki page for general information on each subsystem and who is in charge, and where to find further information
• Updates from Radiation shielding meeting with JLab
  • Electron EM and neutron radiation in the hall for personnel and electronics.
  • Fringe field in the G4. Where is the map file and what specifications we use in G4 for background studies? Juliette, Ciprian, and Sakib
