RSI075102RH

Inductive conductivity tensor measurement for flowline or material samples

John L. Kickhofel, Amine Mohamide, Jonatan Jalfin, Joshua Gibson, Philip Thomas, Gerald Minerbo, Hanming Wang, and Dean M. Homan

We present apparatus capable of electrical conductivity tensor measurements in a noninvasive, noncontact, inductive manner with resolution from 5 mS/m. Inspired by the triaxial induction logging technology appearing in the oil patch today, our apparatus is applicable not only to anisotropic geological core analysis but also to arbitrary material samples and flowline systems.

Double conical crystal x-ray spectrometer for high resolution ultrafast x-ray absorption near-edge spectroscopy of Al K edge

A. Levy, F. Dorchies, C. Fourment, M. Harmand, S. Hulin, J. J. Santos, D. Descamps, S. Petit, and R. Bouillaud

Using an ultrafast laser-induced x-ray source, this optical device based on a set of two potassium acid phthalate conical crystals allows the extraction of x-ray absorption near-edge spectroscopy structures following the Al absorption K edge. The proposed experimental protocol leads to a measurement of the absorption spectra free from any crystal reflectivity defaults and shot-to-shot x-ray spectral fluctuation.

Note: Development of a small maglev-type antirolling system

Cheol Hoon Park, Hee Chang Park, Han Wook Cho, Seok Jun Moon, and Tae Young Chung

Various passive and/or active antirolling devices have been used for suppressing the rolling motion of ships in the ocean. In this study, a maglev-type active mass driver (AMD) is developed for controlling the rolling motion of a shiplike structure

Long-term value from Review of Scientific Instruments

According to journal metrics just released by Thomson Reuters, the Cited Half-Life of Review of Scientific Instruments (RSI) has increased to 8.3 years. This reflects the long-term value and relevancy of research published in the journal. Read more.
