The rate of muons from LHC pp collisions reaching the surface above ATLAS interaction point is measured as a function luminosity and compared with expected rates decays W Z bosons b- c-quark jets. In addition, data collected during periods without beams circulating in provide measurement background cosmic ray inelastic backscattering that to simulation predictions. Data were recorded 2018 2.5 ×...

The need to produce intense X-rays in the Energy Recovery Linear Accelerator requires shorter and narrower electron beams than the Cornell Electron Storage Ring can provide. Such electron beams will demand highly accurate beam position monitors (BPMs) to enable operators to control the beam. To prepare for new BPMs, a test stand has been built to conduct experiments on new algorithms and design...

Today, modeling is critical for cognition and analysis of designers in industry field to meet their needs and design based on design requirements and available facilities to accelerate production and development of components of industrial engines. In this study, one structure has been proposed, designed, and analyzed based on turboshaft marine engine type to test this kind of engine in order t...

The setup of two different small scale teststands for measurements regarding an electron Cherenkov detector as part of the ILC polarimeters is presented. Component measurements already carried out are analyzed and others, foreseen for the near future, are discussed. The larger one of the two teststands features the old Cherenkov detector of the SLD experiment, which will be used as a reference ...
