  • Dave gave a report about his toy monte-carlo studies of proton/kaon/pion separation using time-of-flight
  • We discussed what the next step in the survey of neutral final states started by Bishnu and Justin (looking at final states with 2 photons)
    • Expand survey to include 2π0, 3π0, etc.?
    • Focus on channels that might lead to the first papers from the commissioning data?
      • Exclusive π0 production, looking at Σ beam symmetry?
      • η production cross section?
    • Consensus was to continue the 2γ work started by Bishnu and Justin, focussing on asymmetries/angular distributions while we work out the details of normalization.
  • Sascha reported that pieces are starting to come together for magnetic shielding studies (Hall probe, a Helmholtz coil is available, perhaps a permanent magnet?). Jing and Sascha will start working on setting up for measurements next week.

In particular we need to determine how many layers of mu-metal will be needed and whether we need a soft-iron outer layer as well.
