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.
