Minutes

  • Effect of moving lucite detector inwards has a smaller effect than increasing donut outer radius on the pi/e photo-electron rate
    • Combination of 26 cm lead donut, with shorter (6cm) and shifted lucite (same inner edge of lucite) gives good result
  • Changing concrete and lead radial and longitudinal thickness independently:
      • lead has most impact, but thinner lead at larger radial extent is also good
  • Showermax mirror box bug fixed and wall thickness reduced
    • no effect on ratios
  • Reduce thickness off donut support flanges from 0.75" to 0.01"
    • no effect on ratios
