The application of parahydrogen gas to enhance the magnetic resonance signals of a diversity of chemical species has increased substantially in the last decade. Parahydrogen is prepared by lowering the temperature of hydrogen gas in the presence of a

An Alternative Calculation of the Size-of-Source Effect Uncertainty for Non-uniform Sources

Autor: M. J. Martín, V. Chimenti, J. P. Pérez

For a correct determination of the size-of-source effect (SSE), it is necessary to use a large (e.g., 50-mm diameter) radiation source of uniform spectral radiance. The non-uniformity of the source can be an important component of the uncertainty bec

The design of X-band multi-cell RF structures for particle accelerators requires an accurate estimation of the sensitivity to the mechanical deformations induced by the surface power loss on the metallic walls. The prediction of these effects is impo

Short copper standing wave (SW) structures operating at an X-band frequency have been recently designed and manufactured at the Laboratori Nazionali di Frascati of the Istituto Nazionale di Fisica Nucleare (INFN) using the vacuum brazing technique. H

Experimental verification of sparse frequency linearly frequency modulated ladar signals modeling

Autor: Eric S. Bailey, Peter E. Powers, Joseph W. Haus, Robert V. Chimenti, Matthew P. Dierking

Publikováno v: Optics express. 18(15)

We present the results of an experiment designed to verify the results of a previously published theoretical model that predicts the range resolution and peak-to-side lobe ratio of sparse frequency linearly frequency modulated (SF-LFM) ladar signals.
