Oriented strand board is a widely used construction material responsible for substantial portion of the fire load many buildings. To accurately model oriented response, kinetics and thermodynamics its thermal decomposition combustion were carefully characterized using milligram-scale testing in part I this study. In current work, Controlled Atmosphere Pyrolysis Apparatus II tests performed on r...

Abstract In this paper, a pyrolysis model for PVC cable is constructed using results from thermogravimetric analysis, microscale combustion calorimeter and cone experiments. The used to simulate fire propagation in horizontal trays. simulated arrangement corresponds tray experiment OECD PRISME 2 project. As laying the cables loosely along trays random process, novel stochastic method developed ...

Phosphomolybdic acid (PMA) as a synergist was added into polyurethane (PU) rigid foam with ammonium polyphosphate (APP) to improve its flame retardancy and thermal stability. The combustion performance of PU studied by limiting oxygen index (LOI), UL-94, cone calorimeter. degradation behavior determined thermogravimetric analysis (TG) infrared spectroscopy (TG-IR). Experimental results showed t...

This report summarizes the quality requirements to the barium fluoride (BaF 2 ) crystals for constructing a high precision electromagnetic calorimeter at future hadron colliders . The basic property of BaF2 crystals and the design and performance of a BaF2 calorimeter are presented . The emphasis of the discussion is in the radiation resistance of the current production BaF2 crystals. An approa...

After 3 years of extensive R&D the Bogoroditsk Techno-Chemical Plant in Russia is ready to enter a preproduction phase where 6000 Lead Tungstate crystals will be produced for the CMS electromagnetic calorimeter during a period of about 18 months. Although this is a demonstration test for the mass production, these crystals will have to be installed in the calorimeter and have therefore to compl...

The CALICE (CAlorimeter for the Linear Collider with Electrons) collaboration [1] plans to examine several technology and geometry options for electromagnetic and hadronic calorimetry at the proposed International Linear Collider. Since in many geometries the total material thickness of the calorimeter is too little to fully contain highly energetic hadronic showers, it is important to gain a g...

An imaging calorimeter has been designed and is being built for the PAMELA satellite-borne experiment. The physics goals of the experiment are the measurement of the flux of antiprotons, positrons and light isotopes in the cosmic radiation. The calorimeter is designed to perform a precise measurement of the total energy deposited, to reconstruct the spatial development of the showers (both in t...

An iron sampling calorimeter with warm-liquid ionization chambers has been tested at the CERN SPS in order to study the signal development and to verify the energy calibration of the hadron calorimeter in the KASCADE-Grande air shower experiment. The absolute energy calibration of the detectors is discussed. Results of the analysis of the lateral and longitudinal shower development in the calor...

The calorimeter and muon systems are essential components to provide a trigger for the LHCb experiment. The calorimeter system comprises a scintillating pad detector and pre-shower, followed by electromagnetic and hadronic calorimeters. The calorimeter system allows photons, electrons and hadrons to be identified, and their energy to bemeasured. Themuon system consists of five measuring station...

The scintillator-strip electromagnetic calorimeter (ScECAL) is one of the calorimeter technologies which can achieve fine granularity required for the particle flow algorithm. Second prototype of the ScECAL has been built and tested with analog hadron calorimeter (AHCAL) and tail catcher (TCMT) in September 2008 at Fermilab meson test beam facility. Data are taken with 1 to 32 GeV of electron, ...
