I will present physics measurements which are achievable in the ALICE experiment at the LHC through the inclusion of a new electromagnetic calorimeter. I will focus on jet measurements in proton proton and heavy ion collisions. Detailed simulations have been performed on jet reconstruction, jet triggering, heavy flavor jet reconstruction through electron identification, gamma-jet reconstruction...

The study of vail roughness effects on model heat transfer in high Reynolds number shock tunnel flows of a few milliseconds duration requires the use of a rugged, fast-response calorimeter of known surface roughness. Models constructed of continuous thin copper sheeting over a solid Insulator substrate with rear thermocouples attached were developed for this purpose. TSut surface of the copper ...

J/ψ suppression as a function of the energy of the zero degree calorimeter : can it discriminate between deconfining and comovers interaction models ? Abstract The ratio of J/ψ over Drell-Yan cross-sections as a function of the energy of the zero degree calorimeter in P b P b collisions has been computed in a comovers interaction model and compared with the results of a deconfining model. The p...

The atmosphere is the calorimeter for HiRes; it is also an essential part of the HiRes readout system. The monitoring of the atmosphere falls into two broad categories: the detailed characterization of the atmosphere as needed for accurate reconstruction of the uorescence light signal, and the detection and tracking of clouds, i.e. opaque or dead regions in the HiRes calorimeter. These monitori...

The activities within the FERMI Collaboration were completed by the successful assembly of multi-chip module demonstrators fulfilling the technical requirements of the LHC generation of high performance detectors like CMS ECAL. Throughout the project, the Collaboration has been concentrating on providing architectures that fulfil the requirements set by the interested experiments in the domain ...

The future experimental program at Jefferson Lab requires an absolute current calibration of a 1 μA CW electron beam to better than 1% accuracy. This paper presents the mechanical and electrical design of a Tungsten calorimeter that is being constructed to provide an accurate measurement of the deposited energy. The energy is determined by measuring the change in temperature after beam exposure...

The Imaging Calorimeter for ACCESS (Advanced Cosmic-ray Composition Experiment for Space Station) is one of several proposed concepts for the ACCESS calorimeter instrument designed to measure the spectrum of protons, helium and heavier nuclei up to ~10 eV. This design utilizes a carbon target and high atomic number absorber sampled by thin layers of scintillating fibers. An engineering prototyp...

Cosmic ray experiments outside the Earth’s atmosphere are subject to severe restrictions on the mass of the instruments. Therefore, it is important that the experimental information that can be obtained per unit detector mass is maximized. In this paper, tests are described of a thin (1.4 λint deep) hadron calorimeter that was designed with this goal in mind. This detector was equipped with two...

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...

The calibration of electromagnetic clusters is one of the key issues of ATLAS (and the LHC) in 2007. The cluster algorithm starting from electronically calibrated calorimeter cells will be described. Local position and local energy variations are corrected for. As a last step, longitudinal weights are applied to correct for energy loss upstream of the calorimeter. Strongly influenced by testbea...
