A transmission-type nonmechanical multiple-angle beam-steering device that uses liquid-crystal blazed grating has been developed. Sixteen steering angles with a contrast ratio of 18 has been demonstrated. A detailed analysis of the liquid-crystal and poly(methyl methacrylate) blazed-grating deflector was carried out to provide guidance during the deflector's development. A manufacturing offset ...

Compensated accelerating structures with longitudinal electric field are well known in the accelerator technology due to high efficiency and parameters stability. For charge particles separation another structures with transverse fields, like travelling wave Disk Loaded Wavegiude (DLW) are used. We propose the standing wave compensated structure with transverse fields for particles rf deflectio...

Monolithically cascaded one-axis micromirrors driven by angular vertical combs are designed and fabricated. Using "W"-shape ray optics, we demonstrate two-axis scanning covering k6.0' two-dimensional area at resonant modes: 7.5kHz, +I 7V in fast-scanning mirror, 1.2kHz, +7V in slow-scanning mirror. INTRODUCTION Because of their independently controllable scanning directions, cascaded one-axis l...

The effects of climate change are growing more and evident, this is caused by the increase in CO2 emissions. Fossil fuel exhaustion need for electricity remote areas have encouraged researchers to advance develop renewable energy sector. One type clean technology vertical water turbines that low efficiency. This paper aims design simulate a novel close-ended, guided deflector improve efficiency...

We have coupled a matrix assisted laser desorption source to an electric beam deflection setup to measure the permanent electric dipole of tryptophan isolated in a molecular beam. The permanent electric dipole is sensitive to the geometry and can be used as a tool to probe the conformation. For tryptophan, the dominant conformation present in the molecular beam has a dipole moment that agrees w...

In the paper we illustrate some possible injection/extraction schemes in the Damping Ring of TESLA using RF deflectors. We illustrate different possible solutions using 2 or 3 RF frequencies in 2, 4 or 6 RF deflector groups both considering the bunches modeled as macro-particles without a finite length and considering a finite bunch length. We discuss, finally, the effects of the errors in the ...
