Hadronic calorimeters and Muon Chambers

The HAC (Hadronic Calorimeter) [9] is positioned both in the barrel region and on the end caps and is enclosing the electromagnetic calorimeters. It provides energy measurement of charged and neutral hadrons and covers the full theta angle between 11^o and 169^o. Muons are the only charged particles that can transverse iron and lead without any strong interaction. Because of this they mainly leave the calorimeters almost unaffected, allowing for $\mu$/$\pi$ separation. Muons are instead detected as tracks in the muon chambers, which are the outer most layer of detectors in the DELPHI experiment.
