Beampipe support geometry and other news

Documentation for the beampipe support geometry description development

After the completion of the 2007 run, the SVT and the SSD were removed from the STAR detector along with there utility lines. The support structure for the beampipe remained, however.

The following drawings describe the structure of the beampipe support as it exists in the late 2007 and probably throughout 2008

STAR AgML Geometry Comparison with STARSIM/AgSTAR

STAR Geometry Comparison: AgML vs AgSTAR

At the left is a general status for each geometry tag which compiles in AgML.  All volumes are tested recursively except for the "IBEM" and similar support structures for the VPD, and the Endcap SMD strips.  (The ESMD planes are tested as a unit, rather than test all 2*12*288 SMD strips).

Color codes:

Green: No differences larger than 1%

Yellow: The volume did not appear in AgSTAR geometry

Orange: Difference was larger than 1%, but absolute difference is absolutely negligible.

Red: A difference larger than 1% was detected for a significant amount of material; or a negligible but widespread difference was detected. 

At the right is a PDF file for each geometry tag. For each volume we show two plots. The top plot shows the absolute number of radiation lengths which a geantino encounters traversing the geometry, starting at the geometry and following a straight line at the given pseudorapidity. We average over all phi. The left (right) hashes show the AgML (AgSTAR) geometry. The difference (expressed as a fractional value) of the two histograms is shown the lower plot. Frequently the differences are small, e.g. 10^-6, and ROOT rescales the plots accordingly. Since it is difficult to read the scales of so many plots at once, we have color coded the plots. (Coding seems to fail in the generation of some histograms)... The meaning of the color coding is summarized below.

R&D Tags

The R&D conducted for the inner tracking upgrade required that a few specialized geometry tags be created. For a complete set of geometry tags, please visit the STAR Geometry in simulation & reconstruction page. The below serves as additional documentation and details.

Taxonomy:

• SSD: Silicon strip detector
• IST: Inner Silicon Tracker
• HFT: Heavy Flavor Tracker
• IGT: Inner GEM Tracker
• HPD: Hybrid Pixel Detector

The TPC is present in all configuration listed below and the SVT is in none.
