Abstract
The performance of the ATLAS electromagnetic Liquid argon/brass forwar d calorimeter with its new readout geometry consisting of tube/rod ele ctrodes with cylindrical shell gaps, has been evaluated with a full de pth prototype in a testbeam experiment with electrons in 1995. The res ults for signal linearity of better than 1% and a constant term in the relative energy resolution of 3% meet and even exceed the original pe rformance requirements very well. Space resolution in the order of 0.5 mm in the high energy limit, and an insignificant signal dependency o n the electron impact angle have been found in addition.
