Calorimeter (particle physics)

<p>In experimental <a href="/facts/Particle_physics/YgIuyj2t">particle physics</a>, a calorimeter is a type of detector that measures the <a href="/facts/Energy/wd8PrQM7">energy</a> of <a href="/facts/Subatomic_particle/tMEzcTWQ">particles</a>.  Particles enter the <a href="/facts/Calorimeter/Njp46oI8">calorimeter</a> and initiate a <a href="/facts/Particle_shower/yxdI5n98">particle shower</a>  in which their energy is deposited in the calorimeter, collected, and measured. The energy may be measured in its entirety, requiring total containment of the particle shower, or it may be sampled. Typically, calorimeters are segmented transversely to provide information about the direction of the particle or particles, as well as the energy deposited, and longitudinal segmentation can provide information about the identity of the particle based on the shape of the shower as it develops. <a href="/facts/Calorimetry/bzA3o7AN">Calorimetry</a> design is an active area of research in particle physics.
