Minutes
- Elham: pion detector simulations with moller and pion generator
- 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
- Effect of moving lucite detector inwards has a smaller effect than increasing donut outer radius on the pi/e photo-electron rate
- Raj: pion detector simulations with beam generator
- rates consistent with moller generator results from Elham
- but photo-electron rates appear consistent with zero
