Agenda

Different concrete/lead donut radius for the newgeometry with shielding in the electron and pion generator (Elham) [1]

Attendance

David, Elham, Raj, Wouter

Local shielding of lucite detectors (downstream/inner radial) works better. This presentation: changing concrete/lead donut radius.
Rate of electrons goes down as radial size is increased: factor 10 decrease when increasing from 16 cm to 35 cm.
When changing the radial thickness of concrete and lead independently, the lead has a much larger impact.
When changing the longitudinal thickness of concrete and lead independently, the lead has a much larger impact as well.
Increasing both the radial thickness while reducing the longitudinal thickness does not result in a change (when keeping volume about the same).
Wouter working on visualization, will pass code to Elham.
Plan: make acrylic smaller in radial extent, keep inner radius the same, reduce outer radius, keep lightguide geometry identical
