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.

This is capped with disk endplates of 6cm steel from r=250cm to 332.8cm
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 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 608.2cmThe 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.
