• Chao - questions about the LAr comparison… Is the task understood? Progress? (no depth meeting this week)
• LRT2013 conference call next week. Who will join?
• We need a plan for funding travel to LRT2013.

• 2nd announcement needs to go soon with agenda.
• Please enter info right here before NEXT WEEK if your name is next to it.

1. Advances and Future Plan in Geant4 (Dennis Wright)
2. Update on FLUKA in context of cosmogenic backgrounds (SLAC, Mario Santana) —Tony confirm with name of talk and person
3. Fluka v Geant comparisons
   1. Tony, Anthony, Allison update on muon production of neutrons —(Anthony name suggestion: Detailed cosmogenic comparison of Fluka and Geant4 physics
   2. Melinda update on FLUKA v Geant in NMM context —Melinda cannot commit to any talks & there's not likely to be anything to report on this topic
   3. Cosmogenic Backgrounds at Sanford Comparison: FLUKA vs Geant4
4. Invited Geant and FLUKA physics Talks rolled into one Summary Talk —(Matthew has agreed)
   • Posted longer talks if they already exist
5. Status of the Depth Task Force Simulations (LAr, LXe, Ge) —Who wants to give this? Prisca?

- Forum on Muon generation

1. Muons generated through GEANT4 (Chao) name please - this should be SHORT 10 min
2. Ideas on how to incorporate MUSUN into GEANT4 (Anthony) Underground Muon Generation in Geant4 - again short.
3. Discussion
4. Any other forums here?

1. Universal Materials Database: Status and plans for LRT2013 (Jodi, 20 min)
2. Status of evaluation of (alpha,n) reaction - (alpha,n) cross sections on different materials, neutron energy spectrum, neutron yield, U and Th content in the rock and different materials
3. Status of Comparison of Cross Sections from EMPIRE and TALYS of Common Materials (Scorza, Palladino, Qiu - 15 min)
4. Discussion and Planning for additional data
   1. Notre Dame, TUNL, Invitation emails are being sent
   2. Planning for how to combine (or not) Materials database, Geant4, alpha-n etc.
   3. talking about radiogenic measurements/stockpiling of materials
   4. Comparison with other predictions

1. The Neutron Multiplicity Meter at Soudan —Yu Chen (Syracuse grad student)
2. SD neutron detector — Chao name of talk
3. Muon system and time stamps —Anthony Coincident Events in Soudan Large Cavern
4. The WATCHMAN Project —Marc Bergevin (UC Davis postdoc)
   • New Bernstein gd-loaded water detector —Anthony to meet with Bernstein at Boulby
5. Other sites and other experiments? HALO site —who will contact them?

1. Recruiting people for the working groups
2. Plans for LRT2013
3. How to organize around the Cosmic Frontier workshop
   • Liason jobs and info gathering?
   • Capabilities tie-in?
   • Screening Facility?

• Universal database = Jodi
• Cosmogenic Group = Angie and Chao
• Fluka v Geant = Anthony and Toni
• Radiogenic data = DongMing
• Neutron benchmarking = Ray and Anthony
