[Solid_ec] Calorimeter dimensions

[Jin Huang]

For question 1: yes. On figure 11 of the calorimeter write-up, i.e. after taken care of the charge sharing, we get about 1cm position resolution on both radial and azimuthal dimension in the case of 10x10 cm modules. It is simulated for various sizes of square modules. And I would expect hexagon module of similar dimension fit on the curve too.

Hello All,

This brings up two issues:

*	Have we done a simulation to see the lateral extent of a shower?  Depending on the lateral extend, the size and to some extent the shape of the individual modules dictates the energy sharing and hence the position resolution.
*	If we decide to not have a regular lattice and go with squares close packed into the center radius, we could mitigate this slightly, but then we would get problems at the PVDIS inner radius, unless we decide to make two separate mounting fixtures
