Recent advances in fire test methods and hazard analysis techniques make it useful to reexamine passenger train fire safety requirements. The use of test methods based on heat release rate (HRR), incorporated with fire modeling and hazard analysis, could permit the assessment of potential hazards under realistic fire conditions. The results of research directed at the evaluation of passenger tr...

1. JET RECONSTRUCTION AT ATLAS The ATLAS calorimeter is non-compensating. Its calibration may be performed either globally or locally. Global calibration is a top-down technique where hadronic objects from specific physics processes are reconstructed relative to a fixed (global) electromagnetic scale. The weights are subsequently applied to calorimeter layers and individual cells based on the d...

The physics programme for an electron-positron linear collider with center of mass energy ranging from 90 GeV to 800/1000 GeV, is largely dominated by events with final state containing many jets [1] (essentially di-boson events with W,Z or Higgs decaying into jets). For an experiment on such an accelerator, the goal of the calorimeter can be either to measure well the total flow of energy (in ...

nanoclay/triphenyl phosphate hybrid system was employed to examine the fire retardancy and mechanical properties of pc/abs blends. each of the polymers and their blends are widely used in the automotive, electrical andelectronic industries. because most thermoplastics are easily combustible they need to be flame retarded to reduce the burning rate especially in the initial phase of a fire incid...

A Forward Plug Calorimeter (FPC) for the ZEUS detector at HERA has been built as a shashlik lead-scintillator calorimeter with wave length shifter fiber readout. Before installation it was tested and calibrated using the X5 test beam facility of the SPS accelerator at CERN. Electron, muon and pion beams in the momentum range of 10 to 100 GeV/c were used. Results of these measurements are presen...

We propose a novel approach to derive longitudinal shower development information from a longitudinally unsegmented calorimeter such as the BABAR electromagnetic calorimeter by utilizing tracking information in conjunction with that of calorimetry. We show that using this information as part of an electron identification algorithm results in a significant reduction in the pion misidentification...

The aim of this paper is to study the combustion characteristics of loose fibrous cellulosic compounds through cone calorimeter measurements. The challenge in studying loose fibrous materials by cone calorimeter in a reproducible manner is met by optimizing various process parameters such as sample weight, heat flux and grid type. The method is validated using cotton fibres and fabrics with a r...

The NA62 experiment [1] at CERN SPS (Super Proton Synchrotron) accelerator will be focused on precision tests of the Standard Model via studies of ultra-rare decays of charged kaons. The high resolution Liquid Krypton (LKr) calorimeter of the former NA48 experiment [2], together with other detectors, will provide a photon-veto with hermetic coverage from zero out to large angles from the decay ...

We present test results and characterization of a data compression system for the readout of the NA62 liquid krypton calorimeter trigger processor. The Level-0 electromagnetic calorimeter trigger processor of the NA62 experiment at CERN receives digitized data from the calorimeter main readout board. These data are stored on an on-board DDR2 RAM memory and read out upon reception of a Level-0 a...

The cryostats of the ATLAS LAr calorimeter system are installed in the ATLAS cavern since several years. Following this, an effort to install and commission the front-end and back-end read-out electronics as well as the timing, trigger and control electronics (infrastructure, crates, and boards) has been ongoing and is finished now, in time for the cavern closure. Following cautious procedures ...
