A prototype electromagnetic liquid argon calorimeter with accordion geometry, using absorber material in all electrodes, has been constructed and tested. This construction results in twice the sampling frequency compared to the conventional accordion electrode structure. The energy resolution, measured with 15 GeV electrons, was found to be 6.3%/√E, in good agreement with the value expected from Monte Carlo simulations.
