This is a version of the Large Detector modelled as of Oct. 1, 2005.

Tracker:
-------
The intermediate tracker is composed of two barrels composed of 0.05616 cm of silicon.
The inner radii and z extent of the two barrel layers are:

The small angle endcap tracker is composed of 5 double sided disks with sensitive slices of 0.03 cm silicon.
The position and size of the disks are:

The central TPC tracker consists of a 250 cm long, 161.8 cm radius sensitive volume filled with P10 gas.
The inner and outer carbon-fiber field cages are at radii of 32. and 161.8 cm.

...

The EM calorimeter is a sampling calorimeter composed of 20 layers of

follow by 10 additional layers with 0.5 cm Tungsten.

Hadron calorimeter:
------------------
The hadron calorimeter is a W scintillator sampling calorimeter composed of 50 layers of

The barrel inner radius is 195 cm with a z extent of +/- 275 cm.
The endcap extends from an inner radius of 26 cm to an outer radius of 260 cm.

Solenoid:
--------
The solenoid is modelled as a cylinder with an inner radius of 250cm. This is larger than the outer radius of the hadron calorimeter since we will not be building a cylindrical detector, but a polygonal one (current thinking is octagonal). The barrel composition is as follows:

This is capped with disk endplates of 6cm steel from r=294.5 cm to 339.8 cm.

Muon System:
-----------
The muon system is implemented as a sampling calorimeter composed of 48 layers of:

The barrel inner radius is 380 cm with z extent of +/- 375 cm.
The endcap sits outside the barrel at an inner z of 380 cm and radius from 26 cm to 690 cm.
