PXL Geometry updates

 A number of presentations has been made on updates needed for the run2013 an onward geometries.
In addition to the Pixel geometries, several changes was needed for the MSC, IDSM and also the BeamPipe.

The geometry for y2013 needs the new beampipe and extensions to east and west. In the old system East and West was
essentially symmetric but no longer. Changes was made to a large number of modules, and the is more to come.

Overall changes have been made to
 
PixlGeo5.xml
PipeGeo3.xml  

for new small diamater beam pipe and extension to east and wet. The west part in Star 
should be identical for z > 159". On the east part the drawing attached shows the new design.
This has been implemented. During this I discovered a number of issues with the old description
of beam pipe. The inner pipe does not end at +- 159" as it should, and diameters were very slightly off (~ 1mm)
Thus I also updated the older PipeGeo.xml; Implications for backward compability for <=y2012 should be evaluated.

PxstGeo.xml
IdsmGeo1.xml
BbcmGeo.xml
This change was due to overlapping volume issue . Not clear the beamPipe area included in the prev BBC master volume was delat with crrectly.
 

geometry.g
Chaned to do proper steering for selecting BP geometry.
- Change done to move def of PIPE as discussed
- select versioning 
 
 
 As can be seen the beam pipe supporting structure will have to be modified for the East. Also the extension as defined in the
drawings from Scheblein do not match the 'old' geant structures for the DX area. the overall drawing will have to be revisited.


 
The supporting structures tare defined in VpddGeo2.xlm. Not something I realy want to touch. The supports have certainly be moved by about 30" (seen in eng. drawing). In addition there are parts that are meant to be BP supports but they are placed in an unphysical place. Obvious when you look at photo's

For completeness the west setup is shown here

 
 
 
-- Some detailed notes can be found in the updated xml files.
 

A short list of items still to be included/modified
- PXL Hinges for support for dtubes (massive)
- PX cables
- Mass termination boards
- cooling tubes
- Cable/cooling supporting frames
- Exterior BH plates and boxes

IDS
- Shroud for both y2012 and y2013

Note:
It does bother me that so far when I have looked at existing code thinhgs show up that are not right
(beam pipe, Vpdd, BBC, IDSM as implemented for 2012,.What QA is in place?
