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.
Beampipe:
The beampipe is composed of three sections: consists of a cylindrical central tube and forward and /backward conical sections.
The . The 0.040cm thick Beryllium central tube has an inner radius of 1.2cm and a z extent of +/- 6.25cm and is made of .040cm thick Beryllium.
extends to |z|<6.25cm. The conical sections have a cone half-angle of 43.4mrad with an inner radius that flares from 1.2 cm at 6.25cm to 8.218cm at |z|=167.9cm.
The conical sections are 0.0875Cm thick Be for 6.25cm<|z|<37.5cm, where they transition to steel.
The thickness of the steel section flares from 0.0875cm at |z|=37.5cm to 0.1992cm at |z|=167.9cm.

Vertex Detector:
The vertex detector is composed of a central barrel system with five layers and forward systems composed of four disks.
Barrels
The barrels are all 12.5cm long and are composed are composed of .0113cm thick Silicon, of which the outer .002cm is sensitive.
The inner radii of the layers are:
1.46cm, 2.26cm, 3.54cm, 4.80cm, and 6.04cm
Sensors are mounted on 13.5cm long support cylinders made of 0.0065cm thick carbon fiber (25% coverage of 0.026cm thick CF).
The cylinders attach to 0.0065cm thick carbon fiber bulkheads that span 1.45cm<r<6.04cm located at |z|=6.75 cm.
The vertex detector supports are 0.0427cm thick carbon fiber cylinders that span 1.45cm<r<16.953cm located at |z|=6.78cm.
Readout electronics and the radial cabling are modeled as disks at the ends of the sensors.

Tracker:
The tracker is composed of five cylindrical barrels with four disk-shaped endplanes. The z extent of the barrels increases with radius and the endplane for each extends beyond its cylinder in radius to provide overlap. The sensitive medium is silicon, assembled into carbon-fiber/Rohacell/PEEK modules and read out via a bump-bonded chip and Kapton/Copper cables. These modules are supported by carbon-fiber/Rohacell/carbon-fiber barrels or disks. Each barrel cylinder is supported from the next barrel out by an annular carbon fiber-ring. Outside each of these support rings in z, G10/Copper printed circuit boards are mounted for power and readout distribution to all silicon modules in a layer.

Forward Disks
There are also three forward disks composed of double-sided sensor modules to measure coordinates in two views. The table below shows the radial extant of the disks and the inner |z| position for the "A" and "B" sensor planes.The forward disk supports are disks made of two 0.05cm thick Carbon Fiber planes separated by a 0.35cm thick layer of Rohacell31. The radial span and inner z coordinate are:
Layer | Inner Radius | Outer Radius | |z| for A Plane | Inner |z| for B Plane |
---|---|---|---|---|
1 | 2.68cm 78cm | 16.87cm 67cm | 20.40 | 20.80cm 21.18cm |
2 | 7.41cm 51cm | 16.67cm | 53.85cm 16.87cm | 54.37cm 25cm |
3 | 11.55cm 65cm | 16.67cm | 82.87cm 95cm | 83.48cm |
The the z-positions and radial extents of the annular support rings that complete the structure of the tracker are:
layer | z | inner radius | outer radius |
---|---|---|---|
1 | 26.7 | 18.5 | 44.1 |
2 | 60.8 | 44.1 | 69.6 |
3 | 94.8 | 69.6 | 95.2 |
4 | 128.9 | 95.2 | 120.8 |
5 | 163.0 | 120.8 | 126.5 |
These rings are composed of 0.15cm thick CarbonFiber. The readout and power distribution boards are mounted on the outside surfaces of these support rings. The regions occupied by these boards and the average thickness of the material they represent are given by:
layer | z | inner radius | outer radius | G10 thickness (cm) | Copper thickness (cm) |
---|---|---|---|---|---|
1 | 27.0 | 23.5 | 43.6 | 0.057 | 0.0038 |
2 | 61.1 | 49.1 | 69.1 | 0.102 | 0.0068 |
3 | 95.1 | 74.6 | 94.7 | 0.108 | 0.0072 |
4 | 129.2 | 100.2 | 120.3 | 0.186 | 0.0124 |
5 | 167.0 | 100.2 | 120.3 | 0.246 | 0.0164 |
