The beampipe consists of a cylindrical central tube and forward/backward conical sections. The 0.040cm thick Beryllium central tube has an inner radius of 1.2cm and 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 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. A titanium liner on the inner surface of the beam pipe consists of a 0.0025cm thick cylinder and 0.0075cm thick conical sections.

The field is solenoidal, constant 5 Tesla along z up to half the coil thickness and -0.6 outside.
Muon System:
The muon system is composed of 11 layers of 20cm thick muon system is composed of 11 layers of 20cm thick Iron plates interspersed with double RPC readout.
The barrel inner radius is 338.8cm with z extent of +/- 294cm.
The endcap sits outside the barrel at an inner z of 303.3cm and radius from 20.0cm to 608.2cm
The field is solenoidal, constant 5 Tesla along z up to half the coil thickness and -0.6 outside.
Segmentation
The readout is 3cm x 3cm squares.
