Items for followup from previous meeting

1. Return "borrowed" SiPMs to Jlab (Regina, USM, and everyone else) Regina is shipping today, USM is shipping shortly, Athens is returning theirs along with Fcal boards
2. Check on status of non-conforming SiPMs (Elton) Hamamatsu has completed their evaluation. Confirm 2 bad. Have agreed to replace all three.
3. Check on radiation hardness of glue (Elton) Based on a conversation with Carl Zorn we do not expect radiation in Hall D should not be an issue for the glue

Minutes

Attending: Elton, Beni, David (JLab); George, Pavlos (Athens); Shaun, Tegan, Zisis, Andrei (Regina); Alam, Elias (USM);

1. Announcements
2. Collaboration Meeting Schedule.
   • Fcal (John Leckey?)
   • Monitoring, especially Fcal (Christina/George?)
   • Update on gluing (Elton). Update slides from Regina and USM are welcome
   • Reconstruction. Will discuss who should give the talk at the next meeting.
3. Review of Action Items
4. Monitoring
   • Finished with Fcal boards and ready to ship
   • Some exchanges related on shipping issues will need to be cleared up with Jarrod.
   • Manuals for Fcal/Bcal monitoring have been passed on for feedback. (Beni agreed to give feedback)
5. Status of testing at Regina
   • Tegan and other students have made PDE measurements down to -13 deg C. They use a styrofoam container with dry ice and measure PDE on the way down.
   • Stopped some measurements due to some noise that they wish to consult with Fernando about.
   • Beni: Could be due to poor contact a low temperature?
   • Will report next week on results.
6. Update from JLab
   • Light Guide Rework Plan
   • General agreement on decision to replace all detached guides. Discussion on process.
   • Consider simulation and cosmics to use as input to understanding and monitoring of detached guides.
   • Series of cosmic runs will be scheduled when students arrive in early June from Regina.
7. Bcal summer activities (contact)
   • Prepare cooling plates for use in readout assemblies (Tom Carstens)
   • Preassembly activities for readout assemblies (Fernando Barbosa, Chris Stanislav, Nic Sandoval)
   • Preparation of light guides (sanding, checking sizes) and covers (forming), assistance with gluing (Tina Mann, Keith Blackburn)
   • Transmission tests of modules (Elton Smith)
   • Cable bundling and installation (Fernando Barbosa)
   • Pulsing system (Hovanes Egiyan)
8. Update from USM
9. Beam Tests, Cosmics: Media:Cosmics_Loose_Report.pdf
   • First results shown and further work will continue
   • Elton: Check cuts on plots in fig 5 and 6.
10. Reconstruction and simulation
    • Irina and Andrei and noted that the shower development at low angles does not seem to follow the angle of the incident track and tends to bend away from the axis. First indications show this is a real effect and may need to be understood and accounted for during calibrations.
