1985 NF Test Facility
Near-field ranges operate by measuring the electromagnetic field near the antenna and then mathematically transforming the data to any arbitrary location. Near-field operations are a form of microwave holography. The wave front measurements are normally made on a planar, spherical or cylindrical surface. This paper discusses primarily the planar configurations as used in the measurement of larg...
متن کاملa new environmental chamber facility
Mexico City’s air pollution is a persistent and pervasive environmental problem that has imposed health and economic costs on society. With Mexico’s expenditures on controls calculated in several millions of pesos per year and slow progress toward compliance with air quality standards, a critical need exits for better and more effective abatement strategies. With the current Federal Environment...
متن کاملBuilding Integrated Photovoltaic Test Facility
The widespread use of building integrated photovoltaics appears likely as a result of the continuing decline in photovoltaic manufacturing costs, the relative ease in which photovoltaics can be incorporated within the building envelope, and the fact that buildings account for over 40 percent of the U.S. energy consumption. However, designers, architects, installers, and consumers need more info...
متن کاملThe JLC Accelerator Test Facility
highest-priority project for the future. Research and development toward the design of such a machine has occurred at KEK for more than a decade. Two major areas of current accelerator R&D at KEK include the technologies needed to generate high-quality beams in an injector complex and high-power microwave technology required for the main linear accelerators. Because its particle bunches encount...
متن کاملAn RPC c irradiation test
LHC muon trigger detectors are supposed to work for 10 yr under an intense #ux of radiation. Therefore, in the framework of ATLAS, the performance of full and reduced size RPC prototypes, heavily irradiated with c sources, were measured for variable incident #uxes. We introduce here a detector description in terms of the `globala parameters based on experimental data such as current, total coun...
