Hi folks,

I modified and committed the Babar magnet in our simulations according 
to the following numbers:

                               inner radius thickness   length
Cryostat inner wall 1420              10.0        3790
Coil and bobbin      1508               93.8       3615
Cryostat outer wall 1745              25.0        3790

The material is Al 5083 (5%Mg, 0.4%Mn). Previously it was an Al cylinder 
of 1/3rd of the normal density. The main difference is that the 
radiation length went from 1 to ~1.4. The cryostat doss not have endcaps 
yet.
