Adds beam pipes

New media.geo used in the generation of beampipes v21e and v21f

v21f has no deflection i.e. no magnetic field v21e has maximum deflection i.e. Gold 2AGeV

Fixes the weight atomic number discrepancy

New definition of the carbon fiber

Inserts materials int the root binary

Includes proper material definitions in both binaries

Corrects the names of the top volumes in both binaries

newly generated binaries to resolve radiation lenght discrepancy

Resolves the naming convention discrepancy

New binaries for downstream beampipe 21e (max deflection), 21f (no deflection), 21g (3.3AGeV), 21h (12AGeV) without internal overlaps

Adds new versions of 21e and 21f files (forgoten in previous commit)

Macros for beampipe geometry creation with VolumeAssembly used to avoid keep volumes Part of the which is supposed to be inside STS back wall is missing due to an unexplanable overlaps. The origin is not affected. create_bpipe_geometry_v21e.C - maximum deflection 2.5 deg create_bpipe_geometry_v21f.C - no magnetic field create_bpipe_geometry_v21g.C - Au+Au 3.3 AGeV/c create_bpipe_geometry_v21h.C - Au+Au 12 AGeV/c

The binaries and macros are not consistent.

The binaries of this commit were not generated by the macros of this commit.

The v21g cannot be suitable for 3.3AGeV/c beams with 100% MF as the beam will be deflected before entering the provided beampipe.

Hello, is for 3.3 AGeV/c 100% MF? I thought it should be 50% for these energies. If I understand the picture correctly, the yellow part is STS and the beam therefore misses even the exit window out of STS.

Unfortunately internal vacuum seems to be missing from these beampipes.

I will merge but further modifications should be done on these macros before the final binaries are created.

Next week, I will take a look on the internal vacuum. Perhaps, we might have some short meeting in case you would need or want anything else.
