The influence of radiation damage on energy resolution, linearity and uniformity of an electromagnetic lead/scintillator calorimeter was studied experimentally with 1–6GeV electrons. Plastic scintillators and wavelength shifter bars were irradiated uniformly with γ rays. Both were identical with those of the ZEUS uranium calorimeter. The attenuation length of the scintillators was determined fr...

ATLAS has chosen for its Hadronic End-Cap Calorimeter (HEC) the copper-liquid argon sampling technique with flat plate geometry and GaAs pre-amplifiers in the argon. The contruction of the calorimeter is now approaching completion. Results of production quality checks are reported and their anticipated impact on calorimeter performance discussed. Selected results, such as linearity, electron an...

Three large open pool fire experiments involving a calorimeter the size of a spent fuel rail cask were conducted at Sandia National Laboratories’ Lurance Canyon Burn Site. These experiments were performed to study the heat transfer between a very large fire and a large cask-like object. In all of the tests, the calorimeter was located above the center of a 7.93m diameter fuel pan, elevated 1m a...

Biobased flame-retardant polylactic acid composites were prepared using ammonium polyphosphate (AP), lignin, and a raw montmorillonite (ANa) as the intumescent formulation. The concentration of AP ANa was varied in order to study its influence on flammability properties composites. samples submitted cone calorimeter test, thermogravimetric analysis coupled Fourier-transform infrared spectroscop...

Lithium-ion batteries (LIBs) are employed when high energy and power density required. However, under electrical, mechanical, or thermal abuse conditions a runaway can occur resulting in an uncontrollable increase pressure temperature that lead to fire and/or explosion, projection of fragments. In this work, the behavior LIBs is analyzed. To purpose, tests on NCA 18,650 cells performed cone cal...

Fire-retardant (FR) treated wood-based panels, used commonly in furniture and construction, need to meet stringent fire safety regulations. This study presents a novel treatment for imparting resistance wood composites by applying separate solutions of phytic acid sodium silicate onto particles before the hot pressing at 160 °C. A scanning electron microscopy-energy dispersive X-ray spectroscop...

Electrical cable sheaths are the most abundant fire load in nuclear power plants, mainly rooms that kept under slight pressure. This configuration leads fires to grow under-ventilated and vitiated conditions. Assessing threat involves characterizing heat released, responsible for growth, smoke evolved, which may interact with sensitive components area. For purpose, a revisited controlled-atmosp...

Electromagnetic calorimeters with noble liquids and their limits in resolution are discussed. The origins of “initial” current measurement in calorimetry are retraced and the performance and first results of the NA48 calorimeter (quasi-homogeneous calorimeter with longitudinal electrode structure) are presented. Results of the prototype calorimeters of KEDR (quasi-homogeneous calorimeter with t...
