SUMMARY NOTES
SIMULATIONS POWER DEPOSITION (Gabriel)
- Apply two-Gaussian to all panels
- Action: make a paramaterization in z (with some segmentation in x) - the quality of the tails in the fit may not be so important
- Also investigate if possible to use lookup tables
SHIELDING MODELING (Josh)
- Investigation of number of blocks - issue found and resolved
- Pb blocks 1867, W blocks ~2200
- expect Pb weight 28 tons, W weight ~20 tons
- Surface quality: if block sizes small should have small tolerances - sensitivity in stacking
- alternative: large W block, e.g. 10 tons or so like for spectrometer collimator?
- Action: status of CUA tests with W blocks
- Action: continue shielding model work
DESIGN/IMPLEMENTATION - THERMAL CALCULATIONS (Amy)
- CPS: length: 20cm, width starts at a few mmm, depth
- Action: investigate why temperature output high, e.g. heat source input too large (should be total 30kW for entire system), assumptions on cooling pipes, etc.
HALLD UPDATES - RADIATION SIMULATIONS (Hovanes)
- Investigating energy deposition - cooling system
- Working on Fluka simulations, modify gap and beam size and investigate energy deposition
- Working on GEANT4 simulations - Jim Ritman team
- Working with JLab RadCon team on another code - for beryllium source and CPS
NEXT MEETING: FRIDAY 4 DECEMBER AT 8:00AM (ET)
