[Alert_collaboration] New design and simulation

[Whitney R. Armstrong]

Raphael,

Can you share the latest cad design files? We need to begin  engineering 
things here and would like to start with the latest design.  

As afar as the inverted end caps, this is an easy fix. I was thinking we 
should study the difference in the simulation (for the forward 
direction). That is, we should work towards a design of the forward 
endcap that minimizes (or uniformly distributes) the total material 
thickness over clas12 forward acceptance. The radiation length Vs 
angle/momentum should be straightforward to extract from the simulation.

Cheers,
Whit
