Thermal safety during the synthesis of a Grignard reagent under different dosing rates was evaluated in this work. A reaction calorimeter (SIMULAR) used to investigate heat release isothermal experiment range 0.5–2.0 g⋅min−1 rates. The thermal decomposition analyzed using accelerating rate calorimetry (ARC). Furthermore, risk assessment runaway matrix and Stoessel criticality diagram. results i...

We report on the study of the eeect of the Tile calorimeter thickness in the ATLAS Barrel calorimeter performance. The reduction of the Tile Calorimeter depth by 20 cm would have severe consequences on the hadron calorimeter performance and would increase the punchtrough probability in the muon chambers placed behind the calorimeter. Cost savings are also analysed.

The FastCaloSim calorimeter simulation was developed to provide a reasonably accurate but still fast simulation of the ATLAS calorimeter system. Parameterizations of electromagnetic and hadronic calorimeter showers are used to deposit particle energies in the detailed calorimeter structure. In the present document a short overview of the fast calorimeter simulation principle is presented. This ...

Addition of sulphoaluminate expansive agent could be one useful method to reduce the shrinkage crack destruction shotcrete. While setting and hardening behavior early age mechanical strength cement pastes containing liquid accelerators may influenced by introduction (SEA). Therefore, in this work, hydration different accelerated with SEA was investigated via times measurement, test, isothermal ...

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...

the present article serves the purpose of pursuing geometrization of heat flow on volumetrically isothermal manifold by means of rf approach. in this article, we have analyzed the evolution of heat equation in a 3-dimensional smooth isothermal manifold bearing characteristics of riemannian manifold and fundamental properties of thermodynamic systems. by making use of the notions of various curva...
