The BABAR Calorimeter Light Pulser System
To make precision measurements with a CsI(Tl) calorimeter in a high luminosity environment requires that the crystals are well calibrated and continually monitored for radiation damage. This should not effect the total integrated luminosity which is particularly important for the BABAR calorimeter to enable it to make CP violation measurements in the B meson system. To achieve this goal a fibre...
متن کاملThe 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 کاملThe CsI ( Tl ) Calorimeter of the BaBar Detector
The Asymmetric B-Factory at the Stanford Linear Accelerator Center will study the B-B meson system with focus on CP violation. Its detector BaBar contains a high-resolution CsI(Tl) calorimeter, which is currently under construction. The nal design of the calorimeter (from the crystals to the calibration system) will be presented in this report. Invited talk presented at the 7th International Co...
متن کاملAbsolute Photon Energy Calibration of the BABAR Calorimeter Using 's
The e ect of residual 0 mass shift after \ideal" single photon calibration is discussed. For the case of the BABAR detector, operating in the (4S) energy region, the shift is estimated to be of the order of 2%. We discuss a new photon energy calibration algorithm using photons produced in 0 and decays. Based on 10 (4S) decays, we achieve a statistical error of better than 0.5% in the photon ene...
