Description

I have been reviewing the material definitions in MAUS and it seems to me that the files need a review.

For the CDB geometry we are missing definitions for Tufnol, TufsetPU, and brass. All of these materials are used in the diffuser. The composition of brass and TufsetPU (polyurethane) are known; they just need to be coded. Tufnol however is a question mark as it is a laminate composed of cotton and a phenolic compound of unknown properties.

There is also a note in src/legacy/Simulation/FillMaterials.cc that bc600 should have 2 oxygen in its chemical structure not 12 (which is used in the material definition). Wikipedia claims that this should be 2 as well, but there is possibly a more informed opinion about this somewhere.

The non-standard materials need to be reviewed, and the missing materials added in the definitions prior to specific evaluations of the energy losses in the materials in question. This should take a few days to complete, once time is allocated, for the materials in use by the geometry.
