This paper summarizes the progress on the construction of a graphite calorimeter for the measurement of absorbed dose to water Dw in medium-energy filtered x-ray qualities, as part of the EMRPfunded project “Metrology for radiotherapy using complex radiation fields” (MetrExtRT, http://radiotherapyemrp.eu/). The design and the construction of a new primary standard for absorbed dose to water (Dw...

The lateral and longitudinal profiles of hadronic showers detected by a prototype of the ATLAS Iron-Scintillator Tile Hadron Calorimeter have been investigated. This calorimeter uses a unique longitudinal configuration of scintillator tiles. Using a fine-grained pion beam scan at 100 GeV, a detailed picture of transverse shower behavior is obtained. The underlying radial energy densities for fo...

The growing importance of electric mobility has led to an increased demand for safety technologies in the automotive sector, such as flame retardancy materials used vehicles. fire protection a fully equipped rechargeable energy storage system (REESS), including battery, housing, control electronics, etc., against fuel must be tested according UNECE Regulation No. 100 Annex 8E - Fire Resistance ...

Polyurethane material is used as an interior finish and wall cavity insulation. Flame-retardant products may be for ignition, flame diffusion, heat-release blocking. A large-scale test was conducted to understand the propagation characteristics of polyurethane with addition a retardant. The fire properties risks four commonly materials were examined using three tests. Specifically, ignition pro...

The uncertainty on the calorimeter energy response to jets of particles is derived for the ATLAS experiment at the Large Hadron Collider (LHC). First, the calorimeter response to single isolated charged hadrons is measured and compared to the Monte Carlo simulation using proton-proton collisions at centre-of-mass energies of √ s = 900 GeV and 7 TeV collected during 2009 and 2010. Then, using th...

We describe R&D results on optical properties of a scintillating tile//ber system for the SDC barrel electromagnetic calorimeter. The tile//ber system uses a wavelength shifting ber to readout the signal of a scintillating plate (tile) and a clear ber to transmit the signal to a phototube. In the SDC calorimeter design, four of tile//ber systems are grouped as a 22 tile package so that the gap ...

The analytical representation of the longitudinal hadronic shower development from the face of a calorimeter is presented and compared with experimental data. The suggested formula is particularly useful at designing, testing and calibration of huge calorimeter complex like in ATLAS at LHC. One of the important questions of hadron calorimetry is the question of the longitudinal development of h...

The H1 detector at HERA has been upgraded by the addition of a new electromagnetic calorimeter. This is installed in the HERA tunnel close to the electron beam line at a position ≃ 8m from the interaction point in the electron beam direction. The new calorimeter extends the acceptance for tagged photoproduction events to the high y range, 0.85 < y < 0.95, and thus significantly improves the cap...

Plastic materials are used increasingly in different domains and the comprehension of phenomena occurring when they exposed to a thermal stress has become huge challenge over years. Indeed, an accurately described decomposition can help both, determining conditions for which ignition occur evaluating their participation fire growth propagation. Numerous parameters influence decomposition, espec...
