CMS ECAL Calibration Strategy
نویسنده
چکیده
The CMS Electromagnetic crystal Calorimeter (ECAL) must be precisely calibrated if its full potential performance is to be realized. Inter-calibration from laboratory measurements and cosmic ray muons will be available for all crystals and has been demonstrated to give good pre-calibration values at the start-up; some crystals will be also inter-calibrated using an electron beam. In-situ calibration with physics events will be the main tool to reduce the constant term of the energy resolution to the design goal of 0.5%. In the following the calibration strategy will be described in detail. Presented at CALOR 2006, Chicago, USA, June 5-9, 2006 Submitted to American Institute of Physics (AIP)

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 ...

Precise in situ calibration of the CMS electromagnetic calorimeter (ECAL) will be of crucial importance to fully exploit the physics reach of the CMS detector. In particular a precise calibration is needed to fully benefit from the excellent energy resolution of the calorimeter, approaching 0.5% for high energy unconverted photons. The resolution for photons is particularly important for the di...

The CMS detector at LHC is equipped with a high precision lead tungstate crystal electromagnetic calorimeter (ECAL). The front-end boards and the photodetectors are monitored using a network of DCU (Detector Control Unit) chips located on the detector electronics. The DCU data are accessible through token rings controlled by an XDAQ based software component. Relevant parameters are transferred ...

We investigate the possibility of reducing the data size of the electromagnetic calorimeter(ECAL) of CMS. The Selective Readout is applied first to reduce the data size at a manageable level. Then various data compression methods are considered, and their performances are estimated using the data from the full simulation of the ECAL system. A reduction of the average event size by a factor of t...
