The performance and granularity of the new calorimeters were set to match the central calorimeter, which was of importance for the triggering system. The electron identification was improved by the use of a completely new central tracking detector assembly, partly consisting of a pioneering silicone-pad detector.
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 ...
The experiment has a photon veto system that provides hermetic coverage between 0 and 50 milliradians. This system is made up of several subsystems covering different angular ranges; the Large Angle Vetos (LAVs) cover 8.5 - 50 mrad, the Liquid Krypton Calorimeter (LKr) covering 1 - 8.5 mrad and the Small Angle Vetos (SAV) covering 0 - 1 mrad.
The list is first compiled from the INSPIRE-HEP database, then missing information is retrieved from the online version CERN's Grey Book. The most specific information of the two is kept, e.g. if the INSPIRE database lists November 1974 , while the Grey Book lists 22 November 1974 , the Grey Book entry is shown.
The calorimeter systems for high energy physics experiments usually consist of three main subsystems: electromagnetic calorimeter (ECAL) to detect electromagnetic showers produced by electrons (or positrons) and photons, hadronic calorimeter (HCAL) to measure hadron-induced showers, and muon tracker (or so-called tail catcher) to identify ...
DELPHI detector at CERN. The electromagnetic calorimetry system consisted of two very forward calorimeters and two small angle calorimeter. The high-density projection chamber (HPC) was a barrel electromagnetic calorimeter mounted on the inside of the solenoid outside the OD. [14]
In SLAC he also worked on operating the liquid-argon calorimeter for the MARK II experiment where his interest in high-performance calorimetry was developed. He became a CERN staff member in 1980 working with the UA2 experiment at the Super Proton Synchrotron collider (major involvement in the discoveries of jets and the W and Z bosons). Worked ...
CASTOR (standing for "Centauro And Strange Object Research") [1] is an electromagnetic (EM) and hadronic (HAD) calorimeter of the CMS experiment at CERN.It is based on plates made out of tungsten and quartz layers, positioned around the beam pipe in the very forward region of the CMS (at 14.385 m from the interaction point), covering the pseudorapidity range 5.1–6.55.
