BCAL inner layer

[Tim Whitlatch <whitey@jlab.org>]

Hi George and Zisis,

If you remember back a couple of months, we discussed using a stainless 
steel layer on the inner most layer of the barrel calorimeter wedges for 
additional stiffness. If this was to take the place of lead, what 
thickness would we want to use (the thicker, the better for stiffness)? 
Of course we would have to have grooves machined to accept the 
fibers.This would also serve as a protective layer for assy and 
installation.

Cheers,
       Tim
