The CMS electromagnetic calorimeter
From 2007 the new CERN proton proton collider will start collisions that could open new perspectives in the fields of high energy particle physics. The CMS experiment at the LHC is in advanced construction phase. In particular new physics could be discovered thanks to the CMS precise electromagnetic calorimeter (ECAL) made of about 75000 scintillating PbWO 4 crystals. A description of the ECAL ...
متن کاملThe CMS Electromagnetic Calorimeter Readout
CMS is a general-purpose detector designed for use in the large hadron collider (LHC) at CERN. The electromagnetic calorimeter will play an important role in electron and photon energy measurements. The benchmark process to evaluate and optimize its performance is H −→ γγ in the intermediate mass range (90 < mH < 150 GeV). For this purpose, each element of the readout chain has to be optimized....
متن کاملCALICE Si/W electromagnetic Calorimeter
The particle flow approach requires calorimeters with ultra-high granularity. The design of the Si/W ECAL has thus been based on this principle. It is composed of 30 layers, each layer having an array of 3 × 3 silicon matrices. These matrices or wafers are divided into 6 × 6 cells with an area of 1 cm. The mechanical structure consists of tungsten plates wrapped in carbon fiber, creating 15 alv...
متن کاملCalice Electromagnetic Calorimeter Readout Status
The CALICE Electromagnetic CALorimeter (ECAL) will be a silicon-tungsten sampling calorimeter [1] with 30 layers of silicon wafers, each containing an 18×18 array of diode pads, giving 9720 channels to be read out. The signal from each pad is amplified by a Very Front End (VFE) ASIC [2] which multiplexes the signals from 18 pads onto one output line. The silicon wafers and VFE chips are mounted...
متن کاملThe CLAS Electromagnetic Calorimeter at Large Angles
The study of the response of the two modules of the large-angle electromagnetic shower calorimeter (LAC) of the CLAS detector to charged and neutral particles is reported. The results agree very well with the Monte Carlo simulation. The procedures adopted for the energy and timing calibration are also discussed, proving that the module geometry allows for simple self-calibrating energy and timi...
