PCB Coil Design Producing a Uniform Confined Magnetic Field

, 2017
We present a magnetic field confining coil with a sub-$10^{-3}$ field uniformity over a large fraction of the coil. The structure is entirely made out of printed circuit boards (PCBs). The PCB design allows to tailor the path of wires to fit the required

80hk Momentum Separation with Bloch Oscillations in an Optically Guided Atom Interferometer

, 2013
We demonstrate phase sensitivity in a horizontally guided, acceleration-sensitive atom interferometer with a momentum separation of 80hk between its arms. A fringe visibility of 7% is observed. Our coherent pulse sequence accelerates the cold cloud in an

Using a magnetic gradiometer in a borehole inclinometer to compensate for external magnetic interference

Научно-технический вестник информационных технологий, механики и оптики
In measurements of the magnetic azimuth of the borehole axis, calculations are based on the superposition of the Earth’s magnetic field and parasitic fields from the remanent magnetization of the geophysical tool assembly and the drill string.

Reconstruction of the Planоgraphy of the Golden Horde Period Caravanserai Kulish (Western Kazakhstan) on the Basis of a Magnetic Survey

Поволжская археология
At the initial stage of studying the Kulish caravanserai, magnetic reconnaissance was carried out for the purpose of non-destructive studying of the planоgraphy of the monument before archaeological excavations. Magnetic exploration was carried out using
