A sandwich type lead-scintillator electromagnetic calorimeter with wav
elength shifter optical readout has been successfully operated at the
DESY ep collider HERA in the H1 detector for three years. The mechanic
al design of the calorimeter together with the associated electronics
and the inclusive electron trigger as well as its performance and stab
ility in test beams and at the ep collider HERA are described in detai
