v21[a-e] STS geometries
STS binaries files:
New STS geometries which are shifted upstream by 4cm and have an updated pitch between stations.
v21a has stations with extended pitch, uses the old beam pipe, repositions the FEB boxes, and changes the material(Airex) for foam in the sts wall. v21b has stations with the extended pitch, repositioned central ladders according to 40 mm diameter beam pipe and new material(Airex) for foam in the STS wall. v21c has stations with extended pitch, repositioned central ladders according to 55 mm diameter beam pipe and new material(Airex) for foam in STS wall foam v21d has stations with extended pitch, reposition of central ladders due to provision for a 40 mm diameter beam pipe. The back side wall has a honeycomb structure Airex material used
v21a sts geoemtry -> v21a beam pipe, v21b sts geoemtry -> v21b beam pipe, v21c sts geoemtry -> v21c beam pipe, v21d sts geoemtry -> v21b beam pipe, v21e sts geoemtry -> v21e beam pipe,
GDML files: [v21a-d] has a repositioned FEBs boxes, C-frames, New Airex material.
