This is the version of the Silicon Detector modelled as of November, 2006, post Valencia.
The compact description of this detector in xml format can be found at http://www.lcsim.org/detectors/sid01.zip . What follows is a plain text description of the file compact.xml found in this zip file.
Where a material is listed as xx% coverage, the density of the material has been reduced to xx% of its nominal value to mimic the effect of cutouts in the material.
The tracking region is defined to be a cylinder with radius 126.5cm and z extent +/- 167.9cm.
