-    The Hadron Calorimeter (HCAL) is used to measure the energy of hadrons, particles made of quarks and gluons. Some examples of them are protons, neutrons and pions. It also helps us detect neutrinos but indirectly. Energy needs to be conserved, so if we observe missing enery, this indicates neutrinos.
