a Calorimeter in CERN. In experimental particle physics, a calorimeter is a type of detector that measures the energy of particles. Particles enter the calorimeter and initiate a particle shower in which their energy is deposited in the calorimeter, collected, and measured. The energy may be measured in its entirety, requiring total containment ...
This occurs with an electromagnetic calorimeter, in the form of photons and/or electron+positron pairs. The energy of the particle may be then measured by the intensity of scintillation light produced by the various scintillator slices. An example detector that uses a shashlik electromagnetic calorimeter is the LHCb detector. [2]
The hadronic calorimeter works in much the same way except the hadronic calorimeter uses steel in place of lead. [9] Each calorimeter forms a wedge, which consists of both an electromagnetic calorimeter and a hadronic calorimeter. These wedges are about 2.4 m (8 ft) in length and are arranged around the solenoid. [29]

This method covers the full range of electromagnetics (from static up to high frequency) and optic applications and is the basis for commercial simulation tools: CST Studio Suite developed by Computer Simulation Technology (CST AG) and Electromagnetic Simulation solutions developed by Nimbic.
The opened Belle II detector before installation of the inner tracking detectors.. The Belle II experiment is a particle physics experiment designed to study the properties of B mesons (heavy particles containing a bottom quark) and other particles.
The 1985-1987 upgrade of the detector was aimed at two aspects: full calorimeter coverage and better electron identification at lower transverse momenta. [11] The first aspect was addressed by replacing the end-caps with new calorimeters that covered the regions 6°-40° with respect to the beam direction, thereby hermetically sealing the detector.
The innermost layer is a silicon-based tracker. Surrounding it is a scintillating crystal electromagnetic calorimeter, which is itself surrounded with a sampling calorimeter for hadrons. The tracker and the calorimetry are compact enough to fit inside the CMS solenoid, which generates a powerful magnetic field of 3.8 T. Outside the magnet are ...
