VTX ladder reorganization

First do the ladders for layers 3 and 4, each consisting of 6 independently placed elements.
Left: Before, 6 volumes [SI03, SP03, SIR4(2), SIR5(2)], some containing other elements, were placed separately into the master volume SICG.

Right: In the new organization, all elements making up the layer 3 and 4 ladders are placed in a single holder volume, SJ03, SJ04 for layers 3 and 4, respectively.

Now you can easily pick up one (layer 3,4) ladder and shift it.
Next, the pixels, layer 1 and 2 ladders.
The cage SICG contains the N and S FVTX SCMN and SCMS, which in turn hold the 4 FVTX cages SCM1-4.

On the bottom, SVXE and SVXW are the barrel halves, containing 4 layers each, layer 1 West (L1_W) through layer 4 East (L4_E).

Layer 4 East (L4_E) contains 12 ladders SJ04 etc.

(The volumes in the middle, SKCC-SISP, are hoses, cables, manifolds, frames etc.)

Here is the old organization, where many ladder elements were placd directly into SICG.

The new organization also makes it possible to display ladders with all elements visible. Here is a stipixel ladder from layer 4:

satt * seen 1
satt sj04 seen 0
satt sp04 seen 0
next; draw sj04 80 140 0 40  3 2.0 2.0
      draw sj04 90  90 0 10 16 0.5 0.5
It also makes it easier to display, or enable/disable detector sets. Here only stripixels West are shown. Also shown are the new holder volumes L1_W through L4_E.
After some renaming, the paths to the 'sensitive detectors' in calls to GSDET and GSDETH are as shown

You can see hits on the sensitive silicon SISN.
