The LHC collimation system is installed and commissioned in different phases, following the natural evolution of the LHC performance. To improve cleaning efficiency towards the end of the low beta squeeze at 7TeV, and in stable physics conditions, it is foreseen to complement the 30 highly robust Phase I secondary collimators with low impedance Phase II collimators. At this stage, their design ...

The FLUKA Monte Carlo program is used to predict the distributions of the muons which originate from primary cosmic gamma rays and reach sea level. The main result is the angular distribution of muons produced by vertical gamma rays which is necessary to predict the inherent angular resolution of any instrument utilizing muons to infer properties of gamma ray primaries. Furthermore, various phy...

A series of borotellurite glass system doped with copper oxide was synthesized using the method melt quenching. The density decreases whereas its molar volume increases in respect to concentration. amorphous nature prepared glasses proven utilisation XRD spectra. Meanwhile, samples' elastic properties are determined from measurement longitudinal and shear velocities ultrasonic technique. modulu...
