Items for followup from previous meeting

1. Resolution studies (Blake)
   • Develop criteria for evaluating resolution studies
   • Study impact of inactive material at the end of BCAL on acceptance.
   • Check what configuration (thresholds, step sizes, stack? parameters for secondaries, etc) is being used for the Hall D simulations (Regina)
2. Review options for import/export to Chile (loans, donations, transfers, etc.)
3. From stand-alone MC, or previous notes, collect the distribution of photons expected for numbers of photons for various showers (especially at low energies, e.g. 50 MeV - 200 MeV) and typicall positions (i.e angles) along the calorimeter. (Andrei).
4. JLab to have some informal discussions on various cooling concepts to be presented at the next meeting.[http://www.jlab.org/~huttonc/siPM_layout.ppt cooling}
