Blanket Model since the AO 

Currently the top of the thermal blanket is modeled as 32.7 mm thick.  All dimensions are available from the RM, for example GR v9r1 https://www.slac.stanford.edu/www-glast-dev/cgi/xmlParams?sessionId=1470ea98f085564ae73de7ac067b43fa&cpId=6219#NADDimPrim
From which we see that the top is 1756.34 mm x 1756.34 mm x 32.7 mm

Final Design 

Here is a link to the final design document. 

Note the crown on the top,  Bill asked that we attempt to retain our current volumes and adjust the density accordingly.  We will neglect the crown at this time and continue to model the blanket as simple boxes on the top and four sides.

The blanket is constructed of mulitple layers of material:
Kevlar C21H15N3O3
56 cm radiation length
6 layers on the top, 8 layers on the sides
Nextel Al2O3 (62.5%) SiO2 (24.5%) B2O3 (13%)   
42 cm radiation length
4 layers
Solomide Foam density = 0.005 g/cm3 
No chemical formula is provided
Material properties 0.0036 g/cm2
0.65 cm thickness/layer (density 0.0055 g/cm3)
according to the final design document, Composition similar to that of Kapton. Equivalent thickness of Kapton determined by scaling by the density = 0.010 cm
Radiation length of Kapton 28.2 cm
MLI&Handling Layers density = 1.4 g/cm3
Thickness 0.07 cm total of all materials
Area density 0.098 g/cm2
Radiation length 28.2 cm
From the description sounds like mostly Kapton (C22H10N2O5)  The only other material explicitly mentioned is Germanium, but after consulting with Dave Thompson (GSFC) it was decided that could be ignored..it only contributes 1000 Angstroms, or 0.00001 cm.

 Top

The top has surface area of 32328 cm2 = (179.8 x 179.8)
The inside of the crown provides an additional 2022 cm2 = (158.0 x 3.2) 4

The thickness of the top can be computed as:
MLI&Handling Layers:  0.07 cm
Solomide Foam: 4(0.65 cm)
Nextel: 4(0.043 cm)
Kevlar: 6(0.03 cm)
Total: 3.02 cm
From Section 7:  Top ( 6 layers Kevlar):  0.137 + 0.119 + 0.015 + 0.098 = 0.36 g/cm2
