====Hadron calorimeter====
The [[hadron]] calorimeter absorbs energy from particles that pass through the EM calorimeter, but do interact via the [[strong force]]; these particles are primarily hadrons.  It is less precise, both in energy magnitude and in the localization (within about 0.1&nbsp;radians only).<ref name="PhysicsatLHC"/>  The energy-absorbing material is steel, with scintillating tiles that sample the energy deposited.  Many of the features of the calorimeter are chosen for their cost-effectiveness; the instrument is large and comprises a huge amount of construction material: the main part of the calorimeter – the tile calorimeter – is 8&nbsp;metres in diameter and covers 12&nbsp;metres along the beam axis.  The far-forward sections of the hadronic calorimeter are contained within the forward EM calorimeter's cryostat, and use liquid argon as well, while copper and tungsten are used as absorbers.
