Description

Notes

TKR material audit

end september

update mass of passive material to real values from measurements

known missing mass in current model mostly around active area

CAL material audit

end september

check and update CAL mass and materials

preliminary surveys indicate good model

TKR alignment in MC

quick fix available in GR-v12

fix bug in MC alignment

checking out alternative alignment strategy

New mass simulation

end september

with latest sim-recon package

will be used to re-evaluate TKR hits deficit and CAL energy shift in simulation

Special TKR geometry simulation

available in progress

vacuum layer between silicon layers and tray core

performed to check penetration of delta rays in a more realistic geometry; preliminary results indicate little effect on TKR hits

Low-energy simulations

available in progress

systematic test of LE EM physics list in G4 and range cutoff studies

preliminary results indicate no effect of range cutoffs and a non-perfect control of LE physics list in our simulation

background simulations with higher TKR hits

end september

increase artificially number of TKR hits to mimick BT data

will use alignment bug and will check effect on background rejection

background simulation with shifted CAL energies

end september

artificially scale simulated CAL energies and most important CAL variables to mimick BT data

will check effect on background rejection and reconstruction algorithms

final best physics list

november

final MC tuning possibly

dig deeper into single processes parameterization should flow into the Service Challenge 1 year run. it will includes best physics list and modification to geometry
