N2 - A novel liquid argon calorimeter concept with thin cylindrical shell gaps, meeting the required physics performance for the forward region (|η| > 3) in a high energy, high luminosity hadron collider experiment such as ATLAS, is described. A prototype for the electromagnetic section was built and tested in two electron testbeam runs at the Brookhaven AGS and at the CERN North Area in 1993, covering a total energy range from 2 to 200 GeV. Dependences of the signal on the impact angle and varying inactive material in front of the calorimeter have been studied. Important performance requirements such as signal linearity better than 2%, a sufficient energy resolution with a constant term of about 4% and a very good space resolution of about 0.6 mm have been demonstrated.
