Hall D Geometry Data Base: Central DC
*************************************
version 1.0: Initial version -rtj
version 1.1: Modified straw tube layout -cam
Stereo angle is 6.000 not 6.016 degrees.
Cathode layers removed.
Material in the end plates of the CDC is Aluminum,
not mylar.
version 1.2: Cleanup of previous version.
version 1.3: Fix typos in CDC. Previously the gas volume was
filled with scintillator in mcfast!.
Changed resolution from 200 micron to 150 micron in
the CDC.
version 1.4: a) Reduce the downstream gas plenum thickness to 2.5cm
with Aluminized mylar window 0.1mm thick
this changes the total length of the CDC and the
straws are not in the center of the CDC volume anymore
b) Fill the CDC gas volume with Ar/CO2 instead of Air, same
for the gas plenums.
c) Upstream gas plenum with thick plexiglass cover and aluminum shell
d) Aluminum support rods 12 in total round the outer perifery
e) Carbon fiber downstream endplate is 6mm thick (was 4mm)
f) Removed the PCB upstream and downstream gas plenum
g) Center of the straws is 3.29cm downstream of the CDC volume center
h) Remove all references to geomtry-option-2
version 3.1: updates for compatibility with geant4 -rtj
a) Remove redundant composition "centralDC_gasvol" (CDCG) and
move its former contents into the outer "centralDC" (CDC)
container.
b) Move the "cdcLayers" volume slightly in z to eliminate
overlaps with the upstream and downstream gas plenums.
c) Move the aluminum mesh (CSAM) volume to align with the
center of the straw volume.
d) Remove extra copies of the upstream and downstream plates
in the gas volume, moved to another geometry layer.
e) Add the upstream (CDPU) and downstream (CDPD) end plates
to the "cdcLayers" (DCLS) volume, set geometry_layer=1.
f) Increase the length of the "cdcLayers" (DCLS) volume to
make room for the two end plates and feedthroughs.
g) Complete rewrite of the straw end sections to get a
more accurate description of the end plate regions.
g) Decrease slightly the outer radius of the readout cables
to prevent extrusion from the envelope of the CDC.
version 3.2: fix problems with incorrect embedding and overlaps -rtj
version 3.3: fix problems with overlap of CDG2 with inner straw ring -rtj
