CMS ECAL Calibration Strategy
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 calibr...
متن کاملECAL Front-End Monitoring in the CMS experiment
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 ...
متن کاملCMS ECAL FENIX ASIC design methodology
A technique estimated to decrease risk when developing complex digital ASICs is presented. Specification errors as well as discrepancy between the product and the specification are addressed. The CMS ECAL FENIX ASIC development [1] is presented as an example. The ASIC features a fully synthesizable and highly testable implementation of triple-redundancy. The RAM blocks are individually tested b...
متن کاملQualification of the Front End Cards for the CMS ECAL
The Front End (FE) card is a critical component of the new readout architecture for the CMS ECAL. The module hosts the Front End New Intermediate data eXtractor (FENIX) ASIC that contains the DSP for trigger primitive generation and RAM for the digital pipeline and the primary event buffers. The Front end Automatic Tester (FAT) allows fast fault detection to ensure that the manufacturing proces...
متن کاملThe CMS ECAL project – Overview and status report
An overview is given of the Lead Tungstate (PbWO4) electromagnetic crystal calorimeter for the CMS detector at the Large Hadron Collider (LHC) at CERN in Geneva. This includes a description of the engineering design, the development of the calorimeter components, the read-out system and results obtained in particle beams. Presented at IEEE Nuclear Science Symposium, Toronto, Canada, November 19...
