Minutes

• Updates on pion detector studies (Elham)
  • Changed concrete donut to lead: decreases pions but no impact on electron background at low energies
    • Is more shielding bad? More hadronic interaction of pions, but not affected by shielding
  • Changed showermax lightguide to vacuum: increase rate of low energy electrons
• Pion detector updates (David)
  • What enters and exits the showermax?
    • Picture of primaries leaving the showermax: the transition showermax detectors are where the primaries 'miss' the showermax
    • No pathological angles
• Bayesian pion background correction (Julia, Elham)
