The LHC beam dumping system (LBDS) is used to dispose accelerated protons and ions in a wide energy range from 450 GeV up to 7 TeV. An abort gap of 3 μs is foreseen to avoid sweeping particles through the LHC ring aperture. This paper gives a brief overview of the critical apertures in the extraction region and the two beam dump lines. MAD-X tracking studies have been made to investigate the im...

in this research, effect of the number of nodular graphite particles, as an important characteristic of ductile cast irons, on the distribution of martensite in dual-phase ductile iron has been studied. ductile iron samples were produced by step casting and the samples were then annealed in order to achieve a fully ferritic structure. a special heat treatment was conducted to produce dual matri...

In the present research, effect of micron sized graphite addition on microstructure and tensile failure Al6061 alloy has been studied. The metal matrix composites reinforced with 6, 9 12 varying weight percentages particles were fabricated by novel two step stir cast route which helps in improving wettability particles. synthesized subjected to microstructural studies, density, hardness propert...

on carbon. These particles can interact with the active sites of the carbon to form a species a t the metal-carbon interface which is stable against high-temperature reduction. This interaction may occur via oxygen atoms bonding with both the carbon surface and iron atoms contacting the carbon. This oxygen could be provided by dissociation of the C O ligands during decomposition. The remainder ...

Submicron to micron size particles are produced in the gas phase of sputtering discharges. These particles can contaminate thin films grown by sputter deposition. On the other hand, particle production in a discharge can be desirable when used for manufacturing fine powders. Here, experimental results are presented demonstrating particle production in an argon discharge, using a variety of targ...

Incorporating two-dimensional (2D) diamond nanosheets with fluorescent color centers exhibits great potential in the application of quantum sensing. However, always show poor optical emission chemical-vapor-deposited (CVD) nanomaterials. To address this issue, Si doped diamond/graphite hybrid films were successfully fabricated microwave-plasma CVD device. The consist diamond-core/graphite-shell...

The unique electronic behaviour of monolayer and bilayer graphene is a result of the unusual quantum-relativistic characteristics of the so-called ‘Dirac fermions’ (DFs) that carry charge in these materials. Although DFs in monolayer graphene move as if they were massless, and in bilayer graphene they do so with non-zero mass, all DFs show chirality, which gives rise to an unusual Landau level ...

Hybrid materials using a macroporous sponge and spherical microporous adsorbents have been developed for an effective rapid pretreatment of water samples. Various adsorbents, including methacrylate series, divinylbenzene (DVB), and graphite particles, were utilized for hybridization with a macroporous sponge consisting of polyethylene and polyvinyl acetate, EVA resin. Both the EVA resin and eac...

could be prepared by employing appropriate precursor molecules. Nanotubes containing both boron and nitrogen have Carbon nanotubes containing small amounts of nitrogen are been grown in the electric arc discharge between graphite produced by the pyrolysis of aza-aromatics such as pyridine, cathodes and graphite anodes filled with boron in a nitrogen methylpyrimidine and triazine over cobalt nan...
