Media:KK's MOLLER Task List.pdf
Tasks for Simulation Subsystem to track:
- 1) LA Tech and SBU -- Simulation/Shielding and Activation : Optimizing the shielding design and develop first order practical design that can be passed to engineers, Radiation load on target clam-shell (o-ring) and magnet coils, Activation studies for various components.
- 2) Wouter -- Pion Simulation (Muon Pair Production): could be significant for pion detector
- 3) TBD -- Detectors/Simulation (Slit scattering bkgd): Comprehensive note summarizing the elimination of all 1-bounce and leading 2-bounce sources
- 4) Seamus and Yury -- General/Simulation (Radiative corrections for all physics processes): Incorporate radiative corrections for e-e and inelastic e-p scattering
- 5) Pion and Simulation Group -- Simulation/Pion (Hyperon background estimation): Strategy to evaluate the hyperon bkgd using full suite of detectors
- 6) David and Seamus -- Simulation/Tracking (Optics collimator for Q2): simulated Q2 analysis and the use of tracking GEMs and special collimation
Media:MOLLER-IntDet-DirRev-Tasks.pdf
Tasks which overlap with Integrating Detector Subsystem:
- 7) Pion Group -- Pion Simulation (Beamdump bkgd impact): beamdump bkgds may affect some detectors
- 8) Manitoba and SBU -- Detectors/Simulation (PMT backgrounds): Comprehensive estimate of all bkgds at the main detector PMTs
- 9) UVA Group -- Detector/Simulation (Main detector geometries): Optimize radial and azimuthal ring dimensions to optimize background asymmetry correction determination and systematic (Yuxiang's approach)
- 10) UVA Group -- Simulation (PMT double difference): From Qweak experience, evaluate upper limit to possible systematic from A_T in showerMax and thin quartz
- 11) SBU Group Detectors/Simulation (ShowerMax splashback): Estimate possible bkgds in main detector PMTs from shmx splashback
- 12) SBU Group -- Detectors/Simulation (Detector shielding optimization): Figure out the configuration of heavy- and light-Z shielding (First need shielding Geometry)
- 13) SBU Group -- Detectors/Simulation (Crosstalk evaluation): Evaluate impact on specific detector measurements of bkgd from other sources
Agenda
- Discuss phase change in meeting schedule. Our next meeting could be Nov 9 (maybe too soon after Director Review Task Meeting) or December 7 (note that Nov 23 is Thanksgiving)
- Director's Review task tracking updates

Minutes: Ciprian presented his slides, revealing some concerning variations between Geant versions (4.9.6 for Yuxiang's analysis to 4.10.2.2 for Ciprian's) regarding detector double counting of events and large differences in photon and electron hits vs. events. There also appears to be a serious problem with the seven fold symmetry, possibly indicating problems with magnetic field handling, as the geometry files are identical between analyses. This was done using the most recent master branch, and an issue is being made on github to look into these problems.
