An Electromagnetic Calorimeter for the Silicon Detector (SiD) Concept

To complement LHC capabilities, ILC detectors must reconstruct hadronic final states, including reasonable separability ofW jets from Z jets. The LDC and SiD full detector concept designs include silicon-tungsten (Si-W) electromagnetic calorimeters (ECal) for particle flow reconstruction of jets at the ILC. With high density and segmentation, they are critical to the physics goal jet energy res...

Fast shower simulation in the ATLAS calorimeter

The time to simulate pp collisions in the ATLAS detector is largely dominated by the showering of electromagnetic particles in the heavy parts of the detector, especially the electromagnetic barrel and endcap calorimeters. Two procedures have been developed to accelerate the processing time of electromagnetic particles in these regions: (1) a fast shower parameterisation and (2) a frozen shower...

Beam tests of lead tungstate crystal matrices and a silicon strip preshower detector for the CMS electromagnetic calorimeter

Further tests of lead tungstate crystal matrices made in high energy electron beams in 1996, using new crystals, new APDs and an improved test setup confirm that an energy resolution of better than 0.6% at 100 GeV can be obtained when the longitudinal uniformity of the struck crystal is adequate. Light loss measurements under low dose irradiation are reported. It is shown that there is no loss ...

Capabilities of A Giant Hybrid Air Shower Detector

Recent reports of superhigh energy cosmic rays beyond the expected spectral cuto have intensiied interest in the unknown origin of the highest energy cosmic rays. There is a need for a much larger data base of more precisely measured air showers. This requires new sensitive detectors of enormous aperture. Combining a ground array of particle counters with an optical detector of atmospheric uore...
