(To be submitted to Nucl. Instr. Meth. A) described. electrons, muons, neutrinos (from missing energy), charged hadrons, ·rr°'s and V°'s is of the detector is its ability to identify particles; the performance in identification of hadrons, and the accuracy obtained in energy and angle is given. An essential property of charged tracks is specified. Calorimeters are used to measure photons and neutral accuracy of the tracking detectors to measure the impact parameter and momentumThe performance of the ALEPH detector at the LEP e+e' collider is reviewed.
